  CI: Upgrade to Ubuntu 22.04 to add GCC 12, Clang 13, Clang 14

Notably, this might have caught #18225, as Clang 14 wasn't - and is not yet
until this commit - in OpenSSL's CI.

It makes sense to ensure CI tests compilers used in newer Linux distributions:
* Fedora 36 ships with GCC 12
* Ubuntu 22.04 ships with Clang 14

We switch from 'ubuntu-latest' (which can change meaning but currently points
to ubuntu-20.04) to ubuntu-20.04 for the older existing compilers, and
ubuntu-22.04 for the newer ones added by this commit.

  CI: add Clang 15

We have to use the PPA provided by LLVM because Clang 15 isn't
officially part of Ubuntu 22.04 (or any other Ubuntu release yet),
see https://apt.llvm.org/ for details.
