refactor(compiler): remove unused code

The `fullInheritane` flag from the metadata and the `CopyDefinitionFeature` that it controls appear to no longer be used since `fullInheritance` is always false. The feature appears to have been there to support ngcc which was removed some time ago.

(cherry picked from commit 8277906)
