feat(compiler): mark @NgModules in provider lists for identification at runtime (#22005)

Browse Source 
All of the providers in a module get compiled into a module definition in the
factory file. Some of these providers are for the actual module types, as those
are available for injection in Angular. For tree-shakeable tokens, the runtime
needs to be able to distinguish which modules are present in an injector.

This change adds a NodeFlag which tags those module providers for later
identification.
