Gives a massive boost on NVIDIA for some reason.
RADV defers push constant update, so ALL_STAGES doesn't have
that much of a perf hit.
~20% uplift in RE2, ~5% uplift in CP77 from some quick and dirty testing.
Seems to be heavily content dependent either way.
Also a bug fix, since we would clobber graphics push constants from
compute and vice versa if both graphics and compute used the same root
signature.

As per MSDN, SetName is just a wrapper around SetPrivateData and a specific GUID.
Some apps and tools will use this to retrieve their name back.
So instead, just forward the name to Vulkan in the SetPrivateData call.

Can only support a subset in Vulkan without extra heroics. The DXR API
lets you query things that you technically should know apriori in the
application. We might need to allocate some side-channel buffers on
demand, but let's defer that until actually needed ... :\
DXR is also very awkward in that we have a query which is resolved in
UNORDERED_ACCESS state instead of COPY_DEST state, so we'll have to
ping-pong through some barriers redundantly.

When building acceleration structures, we need to have an
VkAccelerationStructureKHR object, but the D3D12 API just uses a plain
VA = ID3D12Resource::GetGPUVA() + offset.
For this to work, we need to resolve the VA back to VkBuffer + offset.
The only VkBuffer we can lookup is the original backing memory
allocation in the VA map, and that allocation itself must own a view
map, since we cannot tie the VA to any specific ID3D12Resource.
Since creating an RTAS is not the common path, we allocate the view map
on-demand with CAS.

RTAS must stay in this resource state forever. The only way to
synchronize them is UAV barriers.

Allows local root signatures to work correctly and is also a good
optimization since we no longer need to dereference memory (potentially
cold cache lines) to figure out heap offset in command buffer.

If we're signalling and waiting on same physical queue (always true for
current SINGLE_QUEUE define), we can rely on submission boundary
synchronization which doesn't require any extra submissions to resolve.
Avoids awkward GPU driver bubbles with back to back signal -> wait pairs
with timeline.
Observed 2% GPU uplift on RE2 on AMD.

Otherwise, when suballocating memory, GetHeapProperties may
not return the exact same set of flags if we ignore flags
when looking up suitable chunks.

This is still useful as a low-level memory allocation function when
we don't want to bother with buffer offsets or D3D12 validation.

Has one bit set for each vkd3d_queue_family that points to a
unique queue. This can be used to iterate over device queues
without having to check for duplicates manually.

This is necessary to keep the amount of allocated memory manageable
in games that allocate a lot of small heaps or committed resources.

This is designed to work with actual device addresses if supported by

Apparently the docs are lying and RTPSO does not hold references to the
root signatures after all.

Need it here since local root signatures need to know
the physical layout of the record buffer up front.

We will use the same pointer buffer to handle acceleration structures,
so unify this buffer under a new name. Simplifies some of the binding
code since SRV path and UAV path looks more similar now.
Only difference is that UAV path uses BDA -> uint32_t,
and SRV uses BDA -> RTAccelerationStructure.
RT requires BDA, so the fallback descriptor set (storage texel buffer) is never used for RT.
