[PATCH v2 5/9] tests/intel/xe_exec_reset: add gt-stress-reset-rapid-cycle subtest

[nishit.sharma@intel.com]

From: Nishit Sharma <nishit.sharma@intel.com>

This extends concurrent reset and submission stress coverage to a
high-frequency reset scenario while keeping the existing stress harness
unchanged for other subtests.
