Bindless CBV is *pretty* bad on NVIDIA, so add a code path which can
promote descriptor table CBVs into push descriptors.
We can safely do this with Root Signature 1.1 STATIC or
the somewhat obscure STATIC_KEEPING_BUFFER_BOUNDS_CHECKS.
With VOLATILE, which basically all titles are using,
we can still force this behavior through a config flag,
but this is an incorrect speed hack. It works in most
titles however, since bindless CBV is exceptionally rare.
We only hoist descriptors when the root signature range has 1 descriptor
anyway, so we should avoid any reasonable bindless scenario.

There is no need to scan through the Vulkan format list,
especially since texel buffer creation happens in the hot path
in cases where we know we need to create R32UI texel buffer views.

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.

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.

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.

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.

We will need separate descriptor sets to be able to handle typed vs
untyped buffer workarounds.
Also writes multiple descriptors for buffers views to make sure MUTABLE
and SSBO sets are filled (or TEXEL_BUFFER + SSBO for non-mutable).
Applications often get this wrong and use raw buffer in shader where
typed view was written and vice versa.
To mitigate this, just write a typed and untyped view together.

The first range will store the byte offset, the second one will
be the typed buffer range. Typed descriptors should write both.
