[committed] libstdc++: Fix value of __cpp_lib_format macro [PR111826]

[Jonathan Wakely]

Tested x86_64-linux. Pushed to trunk.

I'll check, but I think should be backported to gcc-13 too.

As noted in the PR, we support both features required for the 202110L
value, so we should define it with that value.
