sys-devel/gcc: cleanup and add 12.1.0 for Apple M1

Cleanup old versions, no longer supported by toolchain.eclass.  For
bootstraps where no C++ compiler is available, we'll have to manually
bootstrap a compiler in stage1.

gcc-12.1.0 is "hybrid", it uses normal sources by default (tested on
x64-solaris), and uses M1-capable sources (Ian) on Darwin targets
(tested on x64-macos).

Package-Manager: Portage-3.0.30, Repoman-3.0.3
