Previously we completely ignored entry-points that had not been compiled with Angular, since we do not need to compile them with ngcc. But this makes it difficult to reason about dependencies between entry-points that were compiled with Angular and those that were not. Now we do track these non-Angular compiled entry-points but they are marked as `compiledByAngular: false`. PR Close #29643
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.
