[CI] Compile on M1 natively (#95719)
We have plenty of runners now, let's use them for compilation as well.
To achieve that, remove `xcode-version: "13.3.1"` property and tweak Metal framework detection logic to work with command line tools(which are installed in `/Library/Developer/CommandLineTools`) and SDK is in `/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk`) rather than full Xcode installation.
TODO: Fix/enable OpenMP accelerated native builds (which are currently broken with `OMP: Error #15: Initializing libomp.dylib, but found libomp.dylib already initialized.`), but this matches existing behavior as cross-builds are compiled with OpenMP disabled.
