[libc++] Add GCC12 CI job

[philnik]

• Fix CI

[philnik]

• Disable format tests and enable implicit_deduction_guides.pass.cpp for GCC 12

We should actually switch to GCC 12 instead of adding a new job. We only support the latest-released GCC per our policy. We should also update https://libcxx.llvm.org/#platform-and-compiler-support to say that we support GCC 12 only.

Wouldn't that mean that we only support clang 14 and 15? I thought the logic was "the latest compiler at the time of the last release branch".

[Mordante]

@philnik I'm a bit puzzled by this review. How does this differ from D126667?

Sorry, I completely forgot that you already worked on that.

[Mordante]

No problem, I just was a bit confused; I thought these were comments to my patch ;-)
