We dont set any deployment target when when we use xcrun to create .air file and this issue looks similar to https://developer.apple.com/forums/thread/105719. Also https://developer.apple.com/forums/thread/105719 states that even if they set app deployment target they need to explicitly set deployment in "xcrun metal".

I like Erik's suggestion of using `MACOSX_VERSION_MIN` for `aarch64`, since it's one less place you need to duplicate a constant.
