[RFC PATCH] docs/about/deprecated: Deprecate 32-bit host systems

[Thomas Huth <thuth@redhat.com>]

Testing 32-bit host OS support takes a lot of precious time during the QEMU
contiguous integration tests, and considering that many OS vendors stopped
shipping 32-bit variants of their OS distributions and most hardware from
the past >10 years is capable of 64-bit, keeping the 32-bit support alive
is an inadequate burden for the QEMU project. Let's mark the 32-bit
support as deprecated so we can drop it after a while - this will help
us to cut down our limited CI minutes in the gitlab CI, for example.
