Also move forcewake and stop_rings code from igt_debugfs to igt_gt
since it fits better. And move the hang injection fork helpers from
igt_aux to igt_gt, too.
Also push the intel_gen call into igt_hang_ring while at it.

Align with common igt library style:
- Push the igt_require into the function.
- Push the intel_gen into the function.

After setting up the copy operations, add a hanging batch. This should
mean that we complete the copy and the compare then races against the
GEM reset. Hopefully, this will catch driver bugs where the target
object is no longer accessible after the hang.
Note: hang injection is disabled until the required kernel interface is
completed. But there are useful additional tests here...
