In order to make adding more options easier, expose the full set of
options to the caller.

If we do a global wait while trying to execute spinners in parallel,
it ends badly with a GPU hang.

We current have a single for_each_engine() iterator which we use to
generate both a set of uABI engines and a set of physical engines.
Determining what uABI ring-id corresponds to an actual HW engine is
tricky, so pull that out to a library function and introduce
for_each_physical_engine() for cases where we want to issue requests
once on each HW ring (avoiding aliasing issues).
v2: Remember can_store_dword for gem_sync
v3: Find more open-coded for_each_physical

We queue N low priority hanging batches across the engines
and check that our high priority write over takes them.

Subtract the time it takes to do a loop to submit the batch from the
dummy load, so in theory each loop takes a constant time (100ms).

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)
