[PATCH i-g-t] tests/intel/xe_pm_residency: Add an assertion on MI_STORE execution time

[Karthik Poosa]

MI_STORE_DWORD generally completes within couple of ms.
Assert if it takes more than 1.2 seconds, as it will cause
IGT test to timeout due to sleep of 120 seconds which is
the current per task timeout.
