ci/gha: Add ARM64 QEMU jobs for clang and clang-snapshot #1414

  1. ci/Dockerfile: Always use versioned clang packages 

    This commit switches to a new strategy to make sure we're installing the
most recent LLVM packages. Before this commit, we used the unversioned
LLVM packages (e.g., `clang` instead of `clang-18`), which are supposed
to provide the latest snapshot, but this is broken for arm64 [1],
which we want to add in a later PR.

Anyway, the new approach is cleaner because it does not require us to
fiddle with the installed `clang` package by removing a symlink.

[1] llvm/llvm-project#64790

  3. ci/Dockerfile: Warn if ulimit -n is too high when running Docker 

    The underlying issue does not affect our CI hosts, but is an issue on my
development machine (Arch Linux). In particular, this affects the vanilla
configuration of Docker on systemd, which has effectively no limit:
https://github.com/docker/packaging/blob/11400a3f5a20f2e3eecc3e6347a2ad9ce41278c7/pkg/docker-engine/common/systemd/docker.service#L31

I hope this saves future generations some precious hours of their life.

  4. ci/Dockerfile: Reduce size of Docker image further 

     - No need to have wget installed
 - Clean up rm -rf /var/lib/apt/lists/, see
