fix(platform-server): align server renderer interface with base renderer (#47868)
fix(platform-server): align server renderer interface with base renderer (#47868)

The `ServerRenderer` wasn't aligned with the `Renderer2` interface which meant that it was still referring to the old `debugInfo` parameters. It also wasn't implementing the `preserveContent` argument of `selectRootElement` which can lead to incosistencies between the server and the client.

Fixes #47844.
