fix(language-service): Do not override TS LS methods not supported by VE NgLS (#42727)
fix(language-service): Do not override TS LS methods not supported by VE NgLS (#42727)

Historically, our Language Service was built with the potential to be a
drop-in replacement for the TypeScript Language Service with the added
benefit of being able to provide Angular-specific information as well.
While our VSCode extension does not use the Language Service in this
way, it appears that other community-contributed plugins do. We don't
really officially support this use-case but there's not real reason for
us to override the TypeScript Language Service's
implementation in the VE Angular Language Service so that it returns
`undefined`. As with other non-implemented methods, we can just allow
this to be deferred to TSLS.
