dev-util/mingw64-runtime: add 12.0.0

ucrt becomes the (upstream) default in this version, but this default
cannot be casually changed in the ebuild as it'd break without redoing
the bootstrap process (if ever switch, will ideally need a news item).

Also have not really tested how ucrt interacts with building Wine,
so would rather leave this alone for a while.

Users that know what they're doing can still flip the USE.
