c++: add -fabi-version=21
I'm about to add a bugfix that changes the ABI of noexcept lambdas, so first
let's add the new ABI version. And I think it's time to update the
compatibility version; let's bump to GCC 13, before the addition of concepts
mangling.
gcc/ChangeLog:
* common.opt: Add ABI v21.
gcc/c-family/ChangeLog:
* c-opts.cc (c_common_post_options): Bump default ABI to 21
and compat ABI to 18.
gcc/testsuite/ChangeLog:
* g++.dg/abi/macro0.C: Update for -fabi-version=21.
