[PATCH 13/20] accel: Forward-declare AccelOpsClass in 'qemu/typedefs.h'

[Philippe Mathieu-Daudé]

The heavily imported "system/cpus.h" header includes "accel-ops.h"
to get AccelOpsClass type declaration. Reduce headers pressure by
forward declaring it in "qemu/typedefs.h", where we already
declare the AccelCPUState type.

Reduce "system/cpus.h" inclusions by only including
"system/accel-ops.h" when necessary.
