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.
