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

The wedged test flow intentionally triggers hang/reset behavior that can
emit a known multi-line fault dump and CAT error in dmesg during
wedged-mode-toggle and related wedged scenarios. Updated existing
test to extend ignore_wedged_in_dmesg with regex patterns that match:
1. Tile/GT fault header and fault detail lines (ASID, faulted address,
fault type, access type, fault level, engine class/instance)
2. Fault response: Unsuccessful -EINVAL
3. Engine memory CAT error line
