refactor(ngcc): resolve modules based on the provided moduleResolver (#34494)

Browse Source 
The `DependencyHost` implementations were duplicating the "postfix" strings
which are used to find matching paths when resolving module specifiers.
Now the hosts reuse the postfixes given to the `ModuleResolver` that is
passed to the host.
