cmake: Explicitly fail if macOS SDK is too old

Browse Source 
Adds a check to explicitly make sure that the macOS SDK being used is
recent enough to build OBS. OBS code currently has ifdefs for older SDKs
in some but not all places and relies on some frameworks existing that
do not exist on older versions, this should clarify what we require.
This commit sets the minimum SDK to 13.1 as this is what our wiki
currently specifies. This can be increased in the future if required.
