Reformat VVL error message The SYNC-HAZARD-WRITE-AFTER-READ VVL error is no longer observed on TraceTest.special_forces_group_2, removed the error message from skipped VVL error list. The TraceTest.special_forces_group_2 now runs into a different SYNC-HAZARD-READ-AFTER-WRITE VVL error, on Linux AMD GPU. An existing entry in the skipped VVL error list already covers this error message. Reformat that entry by adding the extraProperties, and changing the messageContents1/messageContents2 fields to nullptr for ease of clean up later.
