ISAPC machine was introduced 25 years ago and it's a lot of time since
such machine was around with real ISA only PC hardware practically defunct.
Also it's slowly bit-rots (for example: I was able to boot RHEL6 on RHEL9 host
in only TCG mode, while in KVM mode it hung in the middle of boot)
Rather than spending time on fixing 'the oldest' no longer tested machine type,
deprecate it so we can clean up QEMU code from legacy fixups and hopefully
make it easier to follow.
Folks who have to use ancient guest that requires ISAPC can still
use older QEMU to play with it.
