Add virtio-intel native DRM context base preparatory code. Virtio-intel
works by passing ioctl's from guest to host for execution, utilizing
available VirtIO-GPU infrastructure.
This patch adds initial experimental native context support using i915
KMD UAPI.
Compile Mesa with -Dintel-virtio-experimental=true to enable virtio-intel
native context support.

GuC offers a mechanism for KMD/UMD to provide workload hints and one of
that strategy is low latency hint. We can utilize this hint when the
workload is more latency sensitive like compute usecases.

With MTL onwards, creating protected contexts too early
may block for a longer period. To prevent that, use the new
kernel GET_PARAM:I915_PARAM_PXP_STATUS interface to get the
status of PXP support immediately without blocking.
Using this same interface, we can also wait for platform
dependency readiness before attempting to create a protected
context. Use a longer timeout when user explicitly requests
for protected context as the kernel assures readiness will be
achieved.

Again sharing the same function across all Intel drivers.
There is still two additional DRM_IOCTL_I915_GEM_CONTEXT_GETPARAM
calls, one in intel/dev and other in perf.
The first one can't call intel_gem_get_context_param() because of the
build order of libs and the second one because it sets the size
parameter.
Will revisit those calls in future but this is already an improvement.

Engines based contexts operate somewhat different for executing
batches. Previously, we would specify a bitmask value such as
I915_EXEC_RENDER to specify to run the batch on the render ring.
With engines contexts, instead this becomes an array of "engines", and
when the context is created we specify the class and instance of the
engine.
Each index in the array has a separate hardware-context. Previously we
had to create separate kernel level contexts to create multiple
hardware contexts, but now a single kernel context can own multiple
hardware contexts.
Another forward looking advantage to using the engines based contexts
is that the kernel does not plan to add new supported I915_EXEC_FOO
masks, whereas they instead plan to add new I915_ENGINE_CLASS_FOO
engine classes. Therefore some rings may only be usable with an engine
based class.

We also add a helper which contains the standard query+alloc+query
pattern used by anv_gem_get_engine_info(). The caller is required to
free the pointer.
These are declared static inline not because we care about the
performance of these helpers but because we're going to use them in the
intel_device_info code and we don't want a link dependency.
