Keen Yee Liau f723a27a71 refactor(language-service): Consistent naming between ts and ng LanguageService (#34888)
This commit makes the Angular Language Service interface a strict subset
of TypeScript's Language Service by renaming all methods to be
consistent with TypeScript's.

The custom Angular `LanguageService` interface was needed before the
inception of TypeScript tsserver plugin, but is now obsolete since
Angular LS is a proper tsserver plugin.

This allows us to easily adapt to upstream TS changes in the future, and
also allows us to reuse all data types defined in TypeScript.
