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".

Looks good to me also. Please let Phil have a say as well before integrating.

Also please update the title of the PR and the JBS issue (they must be the same) to something about that we're changing metal min version, rather than the obscure error that was the result of not having the min version...
