  [flang][Driver] Enable support for -mmacos-version-min= (#143508)

So far as I can tell this option is driver-only so we can just re-use
what already exists for clang. I've added a unit test based on clang's
unit test to demonstrate that the option is handled.

Still TODO is to ensure that flang-rt is built with the same macos
minimum version as compiler-rt. At the moment, setting the flang minimum
version to older than the macos version on which flang was built will
lead to link warnings because flangrt is built for version of macos on
which flang was built rather than the oldest supported version (as
compiler-rt is).
