drm/i915/selftests: Add request throughput measurement to perf

Under ideal circumstances, the driver should be able to keep the GPU
fully saturated with work. Measure how close to ideal we get under the
harshest of conditions with no user payload.

v2: Also measure throughput using only one thread.
