For certain ExecuteIndirect() uses, we're forced to use this path
since we have no way to update push descriptors indirectly yet.

The runtime is specified to validate certain things.
Also, be more robust against unsupported command signatures, since we
might need to draw/dispatch at an offset. Avoids hard GPU crashes.

For now, just keep the NV path as well. It's the exact same extension
basically as the KHR one.

If we don't get a swapchain on first frame for whatever reason, defer
creating the descriptors.

If we fail to present after a swapchain recreation, force a SURFACE_LOST
scenario and try again later when things hopefully stabilize.

It just called create_vulkan_swapchain anyways.
Also, add in extra parameter to support temporary user buffer fallbacks.

Refactor destroy_buffers to destroy_resources as it's more obvious what
it's doing that way.

Some dynamic state is at risk of being spammed with same arguments many
times. For the dynamic state that is trivial to check, do so.
Ghostwire: Tokyo has been observed to spam the same OMSetStencilRef
value causing some context rolls, also RSSetShadingRate has been set
redundantly.

When the disk cache is used, the cache we give back to applications is a
dummy. Therefore, try to use the disk cache blob if we detect a useless
application blob.

With VKD3D_SHADER_CACHE_PATH, we can add automatic serialization of pipeline
blobs to disk, even for games which do not make any use of GetCachedBlob
of ID3D12PipelineLibrary interfaces. Most applications expect drivers to
have some kind of internal caching.
This is implemented as a system where a disk
thread will manage a private ID3D12PipelineLibrary, and new PSOs are
automatically committed to this library. PSO creation will also consult
this internal pipeline library if applications do not provide their own
blob.
The strategy for updating the cache is based on a read-only cache which
is mmaped from disk, with an exclusive write-only portion for new blobs,
which ensures some degree of safety if there are multiple
concurrent processes using the same cache.
The memory layout of the disk cache is optimized to be very efficient
for appending new blobs, just simple fwrites + fflush.
The format is also robust against sliced files, which solves the problem
where applications tear down without destroying the D3D12 device
properly.
This structure is very similar to Fossilize, and in fact the idea is to
move towards actually using the Fossilize format directly later.
This implementation prepares us for this scenario where e.g. Steam could
potentially manage the vkd3d-proton cache.
The main complication in this implementation is that we have to merge
the read-only and write caches.

For internal pipeline libraries, we want a somewhat different strategy.
- PSOs are keyed by hash instead of user key.
- We want the option to conditionally store SPIR-V and PSO blobs.
For internal caches, there isn't much of a reason to store PSO blobs
since the disk cache is going to be primed anyways.
