Re: [RFC PATCH-for-8.1] accel: Remove HAX accelerator

HAX is deprecated since commits 73741fda6c ("MAINTAINERS: Abort HAXM maintenance") and 90c167a1da ("docs/about/deprecated: Mark HAXM in QEMU as deprecated"), released in v8.0.0. Per the QEMU deprecation policy, we shouldn't remove it before QEMU release v8.2.0. However per the latest HAXM release (v7.8), the latest QEMU supported is v7.2: Note: Up to this release, HAXM supports QEMU from 2.9.0 to 7.2.0. (https://github.com/intel/haxm/releases/tag/v7.8.0) The next commit (https://github.com/intel/haxm/commit/da1b8ec072) added: HAXM v7.8.0 is our last release and we will not accept pull requests or respond to issues after this. As of commit b455ce4c2f, it became very hard to build and test HAXM. Its previous maintainers made it clear they won't help. It doesn't seem to be a very good use of QEMU maintainers to spend their time in a dead project. Save our time by removing this orphan zombie code before the QEMU v8.2 release.

``-M kernel-irqchip=off`` cannot be used on KVM if the CPU model includes a local APIC. The ``split`` setting is supported, as is using ``-M kernel-irqchip=off`` when the CPU does not have a local APIC.
