642ce52d8e accel: Move HAX hThread to accelerator context 
hThread variable is only used by the HAX accelerator,
so move it to the accelerator specific context.

f861b3f390 accel: Rename HAX 'struct hax_vcpu_state' -> AccelCPUState 
We want all accelerators to share the same opaque pointer in
CPUState. Start with the HAX context, renaming its forward
declarated structure 'hax_vcpu_state' as 'AccelCPUState'.
Document the CPUState field. Directly use the typedef.

Remove the amusing but now unnecessary casts in NVMM / WHPX.

83d0f7f95c accel: Destroy HAX vCPU threads once done 
When the vCPU thread finished its processing, destroy
it and signal its destruction to generic vCPU management
layer.

Add a sanity check for the vCPU accelerator context.

90c167a1da docs/about/deprecated: Mark HAXM in QEMU as deprecated 
The HAXM project has been retired (see https://github.com/intel/haxm#status),
so we should mark the code in QEMU as deprecated (and finally remove it
unless somebody else picks the project up again - which is quite unlikely
since there are now whpx and hvf on these operating systems, too).

b86f59c715 accel: replace struct CpusAccel with AccelOpsClass 
This will allow us to centralize the registration of
the cpus.c module accelerator operations (in accel/accel-softmmu.c),
and trigger it automatically using object hierarchy lookup from the
new accel_init_interfaces() initialization step, depending just on
which accelerators are available in the code.

Rename all tcg-cpus.c, kvm-cpus.c, etc to tcg-accel-ops.c,
kvm-accel-ops.c, etc, matching the object type names.
