feat(language-service): expose determining the NgModule of a Directive (#32710)

This sets up the Language Service to support #32565.
This PR exposes a `getDirectiveModule` method on `TypeScriptServiceHost`
that returns the NgModule owning a Directive given the Directive's
TypeScript node or its Angular `StaticSymbol`. Both types are supported
to reduce extraneous helper methods.
