[PATCH v2 0/6] Deprecate support for 32-bit x86 and arm hosts

[Thomas Huth]

We're struggling quite badly with our CI minutes on the shared
gitlab runners, so we urgently need to think of ways to cut down
our supported build and target environments. qemu-system-i386 and
qemu-system-arm are not really required anymore, since nobody uses
KVM on the corresponding systems for production anymore, and the
-x86_64 and -arch64 variants are a proper superset of those binaries.
So it's time to deprecate them and the corresponding 32-bit host
environments now.

This is a follow-up patch series from the previous discussion here:

 https://lore.kernel.org/qemu-devel/20230130114428.1297295-1-thuth@redhat.com/

where people still mentioned that there is still interest in certain
support for 32-bit host hardware. But as far as I could see, there is
no real need for 32-bit x86 host support and for system emulation on
32-bit arm hosts anymore, so it should be fine if we drop these host
environments soon (these are also the two architectures that contribute
the most to the long test times in our CI, so we would benefit a lot by
dropping those).

v2:
- Split binary and host deprecation into separate patches
- Added patches to immediately drop the jobs from the CI
