accel: Extract AccelClass definition to 'accel/accel-ops.h'
...
Only accelerator implementations (and the common accelator
code) need to know about AccelClass internals. Move the
definition out but forward declare AccelState and AccelClass.

...
Unfortunately "system/accel-ops.h" handlers are not only
system-specific. For example, the cpu_reset_hold() hook
is part of the vCPU creation, after it is realized.
Mechanical rename to drop 'system' using:
$ sed -i -e s_system/accel-ops.h_accel/accel-cpu-ops.h_g \
$(git grep -l system/accel-ops.h)

accel: Expose and register generic_handle_interrupt()

In order to dispatch over AccelOpsClass::handle_interrupt(),
we need it always defined, not calling a hidden handler under
the hood. Make AccelOpsClass::handle_interrupt() mandatory.
Expose generic_handle_interrupt() prototype and register it
for each accelerator.

The heavily imported "system/cpus.h" header includes "accel-ops.h"
