feat(compiler): implement style encapsulation for new view engine (#14518)

Included refactoring:
- splits the `RendererV2` into a `RendererFactoryV2` and a `RendererV2`
- makes the `DebugRendererV2` a private class in `@angular/core`
- remove `setBindingDebugInfo` from `RendererV2`, but rename `RendererV2.setText` to 
  `RendererV2.setValue` and allow it on comments and text nodes.
