Previously, the (currently disabled) undecorated parent migration in ngcc would produce errors when a base class could not be determined statically or when a class extends from a class in another package. This is not ideal, as it would cause the library to fail compilation without a workaround, whereas those problems are not guaranteed to cause issues. Additionally, inheritance chains were not handled. This commit reworks the migration to address these limitations. PR Close #33362
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.
