[RFC PATCH 0/6] Add support for Mesa GPU hang replay tool

[Matthew Brost <matthew.brost@intel.com>]

Add support for the Mesa GPU hang replay tool, which exists in the i915.

The main changes are as follows:

- Update devcoredump to include additional information, allowing the
  Mesa tool to extract everything it needs to replay a GPU hang. These
  updates are designed to remain compatible with the existing Mesa
  devcoredump parser.
- Introduce the DRM_XE_EXEC_QUEUE_SET_HANG_REPLAY_STATE extension, which
  enables setting the execution queue state to the hung execution queue
  state.

This is being sent as an RFC, as the Mesa uAPI tool has yet to be developed. The tool is a prerequisite for merging this change.
