tests: Add gem_spin_batch
Add gem_spin_batch to test that the dummyload infra
is working properly. Can be also act as tool to force
a single engine to be busy for controlled period of time.
v2: plenty of igt-fu improvements (Chris)
v3: nesting batches for more utilization, epsilon fun (Chris)
v4: clear interrupts on start (Chris)
