Having the exec queue snapshot inside a "GuC CT" section was always wrong. Commit c28fd6c358db ("drm/xe/devcoredump: Improve section headings and add tile info") tried to fix that bug, but with that also broke the mesa tool that parses the devcoredump, hence it was reverted in commit 70fb86a85dc9 ("drm/xe: Revert some changes that break a mesa debug tool").
With the mesa tool also fixed, this can propagate as a fix on both kernel and userspace side to avoid unnecessary headache for a debug feature.
