[PATCH 0/2] *** Enable -cpu <cpu>,help ***

[Dinah Baum <dinahbaum123@gmail.com>]

This patch series enables printing the CPU
options using '-cpu cpu,help' as requested in
https://gitlab.com/qemu-project/qemu/-/issues/1480

Sample output:
athlon features:
  3dnow=<qbool>
  3dnowext=<qbool>
  3dnowprefetch=<qbool>
  ...

Part 1 is a refactor patch that enables query-cpu-model-expansion
on all architectures, but doesn't implement any additional
feature probing. Currently only arm, i386, and s390x support
full feature probing.

This lays for the groundwork for Part 2 which actually
implements the '<cpu>,help' feature

Limitations:
Currently only 'FULL' expansion queries are implemented since
that's the only type enabled on the architectures that
allow feature probing

Unlike the 'device,help' command, default values aren't
printed
