file(GET_RUNTIME_DEPENDENCIES): Fix weak macOS libraries not detected

Browse Source 
Starting with Clang 12, `otool -l` reports `LC_LOAD_WEAK_DYLIB` instead
of `LC_LOAD_DYLIB` for weakly linked libraries.  Update the
implementation of `file(GET_RUNTIME_DEPENDENCIES)` to recognize these.

Fixes: #21684
