Subject: [PATCH] cmake: use CMAKE_SYSTEM_PROCESSOR instead of
 CMAKE_OSX_ARCHITECTURES for mlx.metallib install (#13696)

The CMake condition for installing mlx.metallib checks
CMAKE_OSX_ARCHITECTURES, but this variable is only set when explicitly
passed - not auto-detected. The arm64 build was missing this flag,
causing the metallib to not be installed, which then caused codesign
to fail on the unexpanded glob pattern.
