feat(language-service): [ivy] wrap ngtsc to handle typecheck files (#36930)

Browse Source 
This commit adds a Compiler interface that wraps the actual ngtsc
compiler. The language-service specific compiler manages multiple
typecheck files using the Project interface, creating and adding
ScriptInfos as necessary.

This commit also adds `overrideInlineTemplate()` method to the mock
service so that we could test the Compiler diagnostics feature.
