drm/i915: Support replaying GPU hangs with captured context image

When debugging GPU hangs Mesa developers are finding it useful to replay
the captured error state against the simulator. But due various simulator
limitations which prevent replicating all hangs, one step further is being
able to replay against a real GPU.

This is almost doable today with the missing part being able to upload the
captured context image into the driver state prior to executing the
uploaded hanging batch and all the buffers.

To enable this last part we add a new context parameter called
I915_CONTEXT_PARAM_CONTEXT_IMAGE. It follows the existing SSEU
configuration pattern of being able to select which context to apply
against, paired with the actual image and its size.

Since this is adding a new concept of debug only uapi, we hide it behind
a new kconfig option and also require activation with a module parameter.
Together with a warning banner printed at driver load, all those combined
should be sufficient to guard against inadvertently enabling the feature.

In terms of implementation we allow the legacy context set param to be
used since that removes the need to record the per context data in the
proto context, while still allowing flexibility of specifying context
images for any context.

Mesa MR using the uapi can be seen at:
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/27594

v2:
* Fix whitespace alignment as per checkpatch.
* Added warning on userspace misuse.
* Rebase for extracting ce->default_state shadowing.

v3:
* Rebase for I915_CONTEXT_PARAM_LOW_LATENCY.

Merge tag 'drm-intel-gt-next-2024-04-26' of https://anongit.freedesktop.org/git/drm/drm-intel into drm-next

UAPI Changes:

- drm/i915/guc: Use context hints for GT frequency

Allow user to provide a low latency context hint. When set, KMD
sends a hint to GuC which results in special handling for this
context. SLPC will ramp the GT frequency aggressively every time
it switches to this context. The down freq threshold will also be
lower so GuC will ramp down the GT freq for this context more slowly.
We also disable waitboost for this context as that will interfere with
the strategy.

We need to enable the use of SLPC Compute strategy during init, but
it will apply only to contexts that set this bit during context
creation.

Userland can check whether this feature is supported using a new param-
I915_PARAM_HAS_CONTEXT_FREQ_HINT. This flag is true for all guc submission
enabled platforms as they use SLPC for frequency management.

The Mesa usage model for this flag is here -
https://gitlab.freedesktop.org/sushmave/mesa/-/commits/compute_hint

- drm/i915/gt: Enable only one CCS for compute workload

Enable only one CCS engine by default with all the compute sices
allocated to it.

While generating the list of UABI engines to be exposed to the
user, exclude any additional CCS engines beyond the first
instance

***

NOTE: This W/A will make all DG2 SKUs appear like single CCS SKUs by
default to mitigate a hardware bug. All the EUs will still remain
usable, and all the userspace drivers have been confirmed to be able
to dynamically detect the change in number of CCS engines and adjust.

For the smaller percent of applications that get perf benefit from
letting the userspace driver dispatch across all 4 CCS engines we will
be introducing a sysfs control as a later patch to choose 4 CCS each
with 25% EUs (or 50% if 2 CCS).

NOTE: A regression has been reported at

https://gitlab.freedesktop.org/drm/i915/kernel/-/issues/10895

However Andi has been triaging the issue and we're closing in a fix
to the gap in the W/A implementation:
