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
