drm/xe: Add replay_offset and replay_length lines to LRC HWCTX snapshot
Add replay_offset and replay_length lines to LRC HWCTX snapshot with the
idea being this information can be used extract the data which needs to
be pass to exec queue extension DRM_XE_EXEC_QUEUE_SET_HANG_REPLAY_STATE
so GPU hang can be replayed via a Mesa tool.
The additional lines look like:
[HWCTX].replay_offset: 0x%x
[HWCTX].replay_length: 0x%x
