docs/about/deprecated: Deprecate 32-bit x86 hosts for system emulation

Browse source 
Hardly anybody still uses 32-bit x86 hosts today, so we should start
deprecating them to stop wasting our time and CI minutes here.

System emulation on 32-bit x86 hosts (since 8.0)
''''''''''''''''''''''''''''''''''''''''''''''''
Support for 32-bit x86 host deployments is increasingly uncommon in mainstream
OS distributions given the widespread availability of 64-bit x86 hardware.
The QEMU project no longer considers 32-bit x86 support for system emulation to
be an effective use of its limited resources, and thus intends to discontinue
it. Since all recent x86 hardware from the past >10 years is capable of the
64-bit x86 extensions, a corresponding 64-bit OS should be used instead.
