lib/dummyload: Support returning output fence

Support creating spin batches which return an output fence using new
__igt_spin_batch_new_fence / igt_spin_batch_new_fence API.

This will be used fromthe perf_pmu@interrupts test to ensure user
interrupt generation from a batch with controlled duration.

v2: Support out fence with multiple engines as well. (Chris Wilson)
