[PATCH i-g-t 0/1] RFC tests/intel/xe_exec_reset: Filter expected timeout dmesg during reset tests

[Sobin Thomas <sobin.thomas@intel.com>]

During reset testing there are timedout messages with lrc seq no
and seqno coming in CI Dmesg. These logs are causing CI warnings.

Since we are intentionally causing the GPU reset, so timeout messages
are expected behavior rather than actual test failures. These messages
filtered by CI and incorrectly flagged as errors.

This change adds ignore_timeout_dmesg() function that registers a regex
pattern to filter out expected timeout-related dmesg messages:
- "Timedout"
- "timeout"

The function is strategically called before operations that trigger
resets to proactively filter expected messages:
- GT reset operations (xe_force_gt_reset_async/sync)
- Legacy test modes involving resets
- Compute mode tests with GT reset flags
- Thread-based reset testing scenarios

This ensures cleaner test output by suppressing expected noise while
preserving genuine error reporting for actual test failures.
