The ReflectionHost supports enumeration of constructor parameters, and one piece of information it returns describes the origin of the parameter's type. Parameter types come in two flavors: local (the type is not imported from anywhere) or non-local (the type comes via an import). ngcc incorrectly classified all type parameters as 'local', because in the source files that ngcc processes the type parameter is a real ts.Identifer. However, that identifier may still have come from an import and thus might be non-local. This commit changes ngcc's ReflectionHost(s) to properly recognize and report these non-local type references. Fixes #33677 PR Close #33901
Angular Compatibility Compiler (ngcc)
This compiler will convert node_modules compiled with ngc, into node_modules which
appear to have been compiled with ngtsc.
This conversion will allow such "legacy" packages to be used by the Ivy rendering engine.
