MacOS: Using 'Minimum Deployment Target' 10.7 (Lion) and documenting MacOS versions

Note that starting with Xcode 14.3, the upcoming 'Minimum Deployment Target' is 10.13 (High Sierra).
However, we are still using Xcode 14.2 and hence 10.7 is still supported.

Note that I upped the 'Minimum Deployment Target' (again) from 10.5 to 10.7
to align with JOAL/openal-soft, i.e. a guaranteed common denominator.
You may still try to use 10.5.

Note lowest tested MacOS version (from myself) is 10.13.6 w/ x86_64) (High Sierra).
