dev-util/mingw64-toolchain: add 10.0.0_p1 (2.39, 12.2.0) unkeyworded

For testing new binutils/gcc impact on wine and friends, may
potentially wait until next mingw release to keyword depending
on schedule or issues.

wine-staging-7.15 at least builds with this but haven't tested
runtime, other versions, nor looked up potential known issues yet
