drm/xe: Implement DRM_XE_EXEC_QUEUE_SET_HANG_REPLAY_STATE

Implement DRM_XE_EXEC_QUEUE_SET_HANG_REPLAY_STATE which sets the exec
queue default state to user data passed in. The intent is for a Mesa
tool to use this replay GPU hangs.

v2:
 - Enable the flag DRM_XE_EXEC_QUEUE_SET_HANG_REPLAY_STATE
 - Fix the page size math calculation to avoid a crash
v4:
 - Use vmemdup_user (Maarten)
 - Copy default state first into LRC, then replay state (Testing, Carlos)
