drm/i915/selftests: Basic stress test for rapid context switching

Browse source

We need to exercise the HW and submission paths for switching contexts

Plus it's an interesting baseline latency metric.

v2: Check the initial request for allocation errors
v3: Use finite waits for more robust handling of broken code
