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'.
