44246e7170 accel: Make AccelCPUClass structure target-agnostic
Move the target-agnostic parts of "accel/accel-cpu-target.h"
to "accel/accel-cpu.h".

Doing so we need to include missing "hw/core/cpu.h" header
in "accel/accel-cpu.h" otherwise we get:

  include/accel/accel-cpu-target.h:39:28: error: unknown type name 'CPUClass'
     39 |     void (*cpu_class_init)(CPUClass *cc);
        |                            ^

a3d40b5eff tcg: Convert TARGET_SUPPORTS_MTTCG to TCGCPUOps::mttcg_supported field
Instead of having a compile-time TARGET_SUPPORTS_MTTCG definition,
have each target set the 'mttcg_supported' field in the TCGCPUOps
structure.

efe25c260c include/exec: Split out accel/tcg/cpu-mmu-index.h
The implementation of cpu_mmu_index was split between cpu-common.h
and cpu-all.h, depending on CONFIG_USER_ONLY.  We already have the
plumbing common to user and system mode.  Using MMU_USER_IDX
requires the cpu.h for a specific target, and so is restricted to
when we're compiling per-target.

Include the new header only where needed.

b12a0f8566 accel: Rename 'hw/core/accel-cpu.h' -> 'accel/accel-cpu-target.h'
AccelCPUClass is for accelerator to initialize target specific
features of a vCPU. Not really related to hardware emulation,
rename "hw/core/accel-cpu.h" as "accel/accel-cpu-target.h"
(using the explicit -target suffix).

More importantly, target specific header often access the
target specific definitions which are in each target/FOO/cpu.h
header, usually included generically as "cpu.h" relative to
target/FOO/. However, there is already a "cpu.h" in hw/core/
which takes precedence. This change allows "accel-cpu-target.h"
to include a target "cpu.h".

Mechanical change doing:

 $  git mv include/hw/core/accel-cpu.h \
           include/accel/accel-cpu-target.h
 $  sed -i -e 's,hw/core/accel-cpu.h,accel/accel-cpu-target.h,' \
   $(git grep -l hw/core/accel-cpu.h)

and renaming header guard 'ACCEL_CPU_TARGET_H'.
