      This is a limited shim for ShadowDOM css styling.
      https://dvcs.w3.org/hg/webcomponents/raw-file/tip/spec/shadow/index.html#styles

      The intention here is to support only the styling features which can be
      relatively simply implemented. The goal is to allow users to avoid the
      most obvious pitfalls and do so without compromising performance significantly.
      For ShadowDOM styling that's not covered here, a set of best practices
      can be provided that should allow users to accomplish more complex styling.

      The following is a list of specific ShadowDOM styling features and a brief
      discussion of the approach used to shim.

      Shimmed features:

      * :host, :host-context: ShadowDOM allows styling of the shadowRoot's host
      element using the :host rule. To shim this feature, the :host styles are
      reformatted and prefixed with a given scope name and promoted to a
      document level stylesheet.
      For example, given a scope name of .foo, a rule like this:

        :host {
            background: red;
          }
        }

      becomes:

        .foo {
          background: red;
        }

      * encapsulation: Styles defined within ShadowDOM, apply only to
      dom inside the ShadowDOM. Polymer uses one of two techniques to implement
      this feature.

      By default, rules are prefixed with the host element tag name
      as a descendant selector. This ensures styling does not leak out of the 'top'
      of the element's ShadowDOM. For example,

      div {
          font-weight: bold;
        }

      becomes:

      x-foo div {
          font-weight: bold;
        }

      becomes:


      Alternatively, if WebComponents.ShadowCSS.strictStyling is set to true then
      selectors are scoped by adding an attribute selector suffix to each
      simple selector that contains the host element tag name. Each element
      in the element's ShadowDOM template is also given the scope attribute.
      Thus, these rules match only elements that have the scope attribute.
      For example, given a scope name of x-foo, a rule like this:

        div {
          font-weight: bold;
        }

      becomes:

        div[x-foo] {
          font-weight: bold;
        }

      Note that elements that are dynamically added to a scope must have the scope
      selector added to them manually.

      * upper/lower bound encapsulation: Styles which are defined outside a
      shadowRoot should not cross the ShadowDOM boundary and should not apply
      inside a shadowRoot.

      This styling behavior is not emulated. Some possible ways to do this that
      were rejected due to complexity and/or performance concerns include: (1) reset
      every possible property for every possible selector for a given scope name;
      (2) re-implement css in javascript.

      As an alternative, users should make sure to use selectors
      specific to the scope in which they are working.

      * ::distributed: This behavior is not emulated. It's often not necessary
      to style the contents of a specific insertion point and instead, descendants
      of the host element can be styled selectively. Users can also create an
      extra node around an insertion point and style that node's contents
      via descendent selectors. For example, with a shadowRoot like this:

        <style>
          ::content(div) {
            background: red;
          }
        </style>
        <content></content>

      could become:

        <style>
          / *@polyfill .content-container div * /
          ::content(div) {
            background: red;
          }
        </style>
        <div class="content-container">
          <content></content>
        </div>

      Note the use of @polyfill in the comment above a ShadowDOM specific style
      declaration. This is a directive to the styling shim to use the selector
      in comments in lieu of the next selector when running under polyfill.

     * Minimum amount of binding slots required in the runtime for style/class bindings.
     *
     * Styling in Angular uses up two slots in the runtime LView/TData data structures to
     * record binding data, property information and metadata.
     *
     * When a binding is registered it will place the following information in the `LView`:
     *
     * slot 1) binding value
     * slot 2) cached value (all other values collected before it in string form)
     *
     * When a binding is registered it will place the following information in the `TData`:
     *
     * slot 1) prop name
     * slot 2) binding index that points to the previous style/class binding (and some extra config
     * values)
     *
     * Let's imagine we have a binding that looks like so:
     *
     * ```
     * <div [style.width]="x" [style.height]="y">
     * ```
     *
     * Our `LView` and `TData` data-structures look like so:
     *
     * ```typescript
     * LView = [
     *   // ...
     *   x, // value of x
     *   "width: x",
     *
     *   y, // value of y
     *   "width: x; height: y",
     *   // ...
     * ];
     *
     * TData = [
     *   // ...
     *   "width", // binding slot 20
     *   0,
     *
     *   "height",
     *   20,
     *   // ...
     * ];

     * It also produces the creation instruction to register all initial styling values
     * (which are all the static class="..." and style="..." attribute values that exist

     *   styleProp(...)
     *   classProp(...)
     * }
     *

     * This array represents the DOM schema. It encodes inheritance, properties, and events.
     *
     * ## Overview
     *
     * Each line represents one kind of element. The `element_inheritance` and properties are joined
     * using `element_inheritance|properties` syntax.
     *
     * ## Element Inheritance
     *
     * The `element_inheritance` can be further subdivided as `element1,element2,...^parentElement`.
     * Here the individual elements are separated by `,` (commas). Every element in the list
     * has identical properties.
     *
     * An `element` may inherit additional properties from `parentElement` If no `^parentElement` is
     * specified then `""` (blank) element is assumed.
     *
     * NOTE: The blank element inherits from root `[Element]` element, the super element of all
     * elements.
     *
     * NOTE an element prefix such as `:svg:` has no special meaning to the schema.
     *
     * ## Properties
     *
     * Each element has a set of properties separated by `,` (commas). Each property can be prefixed
     * by a special character designating its type:
     *
     * - (no prefix): property is a string.
     * - `*`: property represents an event.
     * - `!`: property is a boolean.
     * - `#`: property is a number.
     * - `%`: property is an object.
     *
     * ## Query
     *
     * The class creates an internal squas representation which allows to easily answer the query of
     * if a given property exist on a given element.
     *
     * NOTE: We don't yet support querying for types or events.
     * NOTE: This schema is auto extracted from `schema_extractor.ts` located in the test folder,
     *       see dom_element_schema_registry_spec.ts

     * A regular expression for breaking a URI into its component parts.
     *
     * {@link https://tools.ietf.org/html/rfc3986#appendix-B} says
     * As the "first-match-wins" algorithm is identical to the "greedy"
     * disambiguation method used by POSIX regular expressions, it is natural and
     * commonplace to use a regular expression for parsing the potential five
     * components of a URI reference.
     *
     * The following line is the regular expression for breaking-down a
     * well-formed URI reference into its components.
     *
     * <pre>
     * ^(([^:/?#]+):)?(//([^/?#]*))?([^?#]*)(\?([^#]*))?(#(.*))?
     *  12            3  4          5       6  7        8 9
     * </pre>
     *
     * The numbers in the second line above are only to assist readability; they
     * indicate the reference points for each subexpression (i.e., each paired
     * parenthesis). We refer to the value matched for subexpression <n> as $<n>.
     * For example, matching the above expression to
     * <pre>
     *     http://www.ics.uci.edu/pub/ietf/uri/#Related
     * </pre>
     * results in the following subexpression matches:
     * <pre>
     *    $1 = http:
     *    $2 = http
     *    $3 = //www.ics.uci.edu
     *    $4 = www.ics.uci.edu
     *    $5 = /pub/ietf/uri/
     *    $6 = <undefined>
     *    $7 = <undefined>
     *    $8 = #Related
     *    $9 = Related
     * </pre>
     * where <undefined> indicates that the component is not present, as is the
     * case for the query component in the above example. Therefore, we can
     * determine the value of the five components as
     * <pre>
     *    scheme    = $2
     *    authority = $4
     *    path      = $5
     *    query     = $7
     *    fragment  = $9
     * </pre>
     *
     * The regular expression has been modified slightly to expose the
     * userInfo, domain, and port separately from the authority.
     * The modified version yields
     * <pre>
     *    $1 = http              scheme
     *    $2 = <undefined>       userInfo -\
     *    $3 = www.ics.uci.edu   domain     | authority
     *    $4 = <undefined>       port     -/
     *    $5 = /pub/ietf/uri/    path
     *    $6 = <undefined>       query without ?
