refactor: deprecate RootRenderer / Renderer

Use `RendererV2` instead of `Renderer` now. `Renderer` can still be injected
and delegates to `RendererV2`.

Use `RendererFactoryV2` instead of `RootRenderer`. `RootRenderer` cannot be used
anymore.

BREAKING CHANGE:
- `RootRenderer` cannot be used any more, use `RendererFactoryV2` instead.
  Note: `Renderer` can still be injected/used, but is deprecated.
