Merge tag 'single-binary-20251030' of https://github.com/philmd/qemu into staging

Various patches related to single binary work:

- Make hw/arm/ common by adding a QOM type to machines to
  tag in which binary (32 or 64-bit) they can be used.
  Convert the Virt and SBSA-Ref machines.
- Build Xen files once
