drm/xe/guc: Enable WA 14018913170

The GuC handles the WA, the KMD just needs to set the flag to enable
it on the appropriate platforms.

v2:
- Fixed CI checkpatch warning, alignment should match open parenthesis.
- Fixed GUC FW version check to use XE_UC_FW_VER_RELEASE which points to
current GUC FW version instead of XE_UC_FW_VER_COMPATIBILITY which
holds GUC FW I/F version (Badal).
v3:
- Removed extra character in debug print.

drm/xe/guc: Include only required GuC ABI headers

On i915 we were adding new GuC ABI headers directly to guc_fwif.h
file since we were replacing old definitions from that file.

On xe driver we could do more and better by including ABI headers
only in files that need those definitions.

drm/xe: Rename engine to exec_queue

Engine was inappropriately used to refer to execution queues and it
also created some confusion with hardware engines. Where it applies
the exec_queue variable name is changed to q and comments are also
updated.

drm/xe: Introduce guc_submit_types.h with relevant structs.

These structs and definitions are only used for the guc_submit
and they were added specifically for the parallel submission.

While doing that also delete the unused struct guc_wq_item.

v2: checkpatch fixes.

drm/xe: Sort includes

Sort includes and split them in blocks:

1) .h corresponding to the .c. Example: xe_bb.c should have a "#include
"xe_bb.h" first.
2) #include <linux/...>
3) #include <drm/...>
4) local includes
5) i915 includes

This is accomplished by running
`clang-format --style=file -i --sort-includes drivers/gpu/drm/xe/*.[ch]`
and ignoring all the changes after the includes. There are also some
manual tweaks to split the blocks.

v2: Also sort includes in headers

drm/xe: Introduce a new DRM driver for Intel GPUs

Xe, is a new driver for Intel GPUs that supports both integrated and
discrete platforms starting with Tiger Lake (first Intel Xe Architecture).

The code is at a stage where it is already functional and has experimental
support for multiple platforms starting from Tiger Lake, with initial
support implemented in Mesa (for Iris and Anv, our OpenGL and Vulkan
drivers), as well as in NEO (for OpenCL and Level0).

The new Xe driver leverages a lot from i915.

As for display, the intent is to share the display code with the i915
driver so that there is maximum reuse there. But it is not added
in this patch.

This initial work is a collaboration of many people and unfortunately
the big squashed patch won't fully honor the proper credits. But let's
get some git quick stats so we can at least try to preserve some of the
credits:
