Update ZAP to pull in MTR_AVAILABLE.

Also defines MTR_AVAILABLE to be empty if MTR_SKIP_AVAILABILITY_ANNOTATIONS is set, sets it in our CI, and removes all the -Wno-unguarded-availability-new. This caused use of "compare:" on UUIDs, which is not available until Mac OS 12.0, hence the update of deployment target to Mac OS 12.0.
