feat(core): speed up view creation via code gen for view factories.

BREAKING CHANGE:
- Platform pipes can only contain types and arrays of types,
  but no bindings any more.
- When using transformers, platform pipes need to be specified explicitly
  in the pubspec.yaml via the new config option
  `platform_pipes`.
- `Compiler.compileInHost` now returns a `HostViewFactoryRef`
- Component view is not yet created when component constructor is called.
  -> use `onInit` lifecycle callback to access the view of a component
- `ViewRef#setLocal` has been moved to new type `EmbeddedViewRef`
- `internalView` is gone, use `EmbeddedViewRef.rootNodes` to access
  the root nodes of an embedded view
- `renderer.setElementProperty`, `..setElementStyle`, `..setElementAttribute` now
  take a native element instead of an ElementRef
- `Renderer` interface now operates on plain native nodes,
  instead of `RenderElementRef`s or `RenderViewRef`s

Closes #5993

- * is used by Angular to efficiently create an instance of this View based on the compiled Template.
- *
- * Most ProtoViews are created and used internally by Angular and you don't need to know about them,
- * except in advanced use-cases where you compile components yourself via the low-level
- * {@link Compiler#compileInHost} API.
- *
- *
- * ### Example
- *
- * Given this template:
- *
- * ```
- * Count: {{items.length}}
- * <ul>
- *   <li *ngFor="var item of items">{{item}}</li>
- * </ul>
- * ```
- *
- * Angular desugars and compiles the template into two ProtoViews:
- *
- * Outer ProtoView:
- * ```
- * Count: {{items.length}}
- * <ul>
- *   <template ngFor var-item [ngForOf]="items"></template>
- * </ul>
- * ```
- *
- * Inner ProtoView:
- * ```
- *   <li>{{item}}</li>
- * ```
- *
- * Notice that the original template is broken down into two separate ProtoViews.
