To increase our testing surface on aarch64 and other hosts, and also to ease
maintenance of docker images, this series introduces x86_64 base containers.
We rely on qemu-user-binfmt (available at least on Fedora and Debian/Ubuntu) to
be installed to execute x86_64 binaries on other host arch.
With this, we can run the full tcg tests suite on any host architecture.

This series exposed an issue with on aarch64 hosts with test
loongarch64-softmmu-memory that was reported in issue:
https://gitlab.com/qemu-project/qemu/-/work_items/4567

--

- Add comment in patch 1 to explain we detect x86_64 containers execution
  capability
- Replace the registry change patch with updated libvirt-ci, that now generates
  arch specific Dockerfiles by default
- Use lcitool --host-arch x86_64 to have stable refresh output on different host
  architectures
- Add a patch to speed up compilation of x86_64/test-avx.c.

I'll send this series in a PR tomorrow, unless there are additional
comments on patches 4, 5, 6.
