package/gcc: switch to gcc 12.x as the default
Even if gcc 11 is still maintained for some time, switch to gcc 12.x
since it has been released since 2022-05-06 and gcc 13.x is available
since 2023-04-26.
We have been having toolchains in the autobuilders with gcc
12.x for a while, so the vast majority of the problems should have
already been solved.
