CMake: Don't hardcode Xcode SDK frameworks into public dependencies

Browse Source 
Using find_library() to find an Xcode framework will end up embedding
the absolute path of the framework into INTERFACE_LINK_LIBRARIES.
A different machine might not have the SDK installed in the same
location, which will cause build failures. This happens in our CI
because Xcode is installed to /Applications/Xcode11.app.

To fix this, replace all system framework paths with
'-framework Foo' flags instead.
We already do this for OpenGL and OpenGL ES.

In the future we might want to convert these into full standalone
FindFoo scripts that expose proper targets.
