Keen Yee Liau 71ada483bf refactor(language-service): Omit typechecking for finding directives (#32156)
Remove unnecessary private method `getDeclarationFromNode` and moved
some logic to utils instead so that it can be tested in isolation of the
Language Service infrastructure.
The use of typechecker to check the directive is also not necessary,
since resolve.getNonNormalizedDirectiveMetadata() will check if the
directive is actually an Angular entity.
