Just use VK_NULL_HANDLE. We rely on the disk cache to exist anyways
here. We never serialize the global pipeline cache, so it might just
confuse drivers into disable disk cache if anything.
Also reduce memory bloat.
Also gets rid of very old NV driver workaround where we forced global
pipeline cache.

Transfer batches buffers CopyTextureRegion calls for batching.
The flushes needs to happen in a few places:
1. ResourceBarrier: This is where the transition from COPY_DEST to other
might happen, at which point the writes must be visible. This might
also transition away from COPY_SRC which invalidates the
precondition.
2. Copy operations. Copies to the same resource are implicitly ordered.
3. Draws and dispatches. These are not strictly necessary, but we don't
want too much command reordering so flushing here seems good.
4. Close. So that we don't throw commands into the void.

Gets better codegen, since compiler no longer has to assume
that negative indices can be generated, which means full 64-bit sign
extension and addressing math (slow).
Based on experiments, no native driver lets -1 indices work,
so it's safe to make the u32 assumption.
See test_root_descriptor_offset_sign as a justification for this change.
Also, see https://gitlab.freedesktop.org/mesa/mesa/-/issues/6562

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

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.
