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.

Refactor push constant invalidation to SetPipelineState,
it is technically more correct to only invalidate when actually pushing

on active bind point there.

Enabling VK_EXT_debug_utils comes at some overhead in Wine due to the object tracking required. There is also likely a non-zero overhead in some native implementations also.
By enabling this conditionally, we can also avoid additional overhead from apps that set debug labels on both the Vulkan and front-end side.
The default condition is to enable it when building with Renderdoc integration or in debug builds.

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.

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

Also writes multiple descriptors for buffers views to make sure MUTABLE

typed view was written and vice versa.

This begins the refactor toward letting us to use both texel buffer and
SSBO descriptors for typed buffers, which is a better workaround than
force_bindless_texel_buffers.
In this new approach, we store a mask in metadata instead of
set/binding.
When copying a descriptor, we will iterate over the masks and look up
binding directly from device->bindless_state.set_info[].
The mask is represented in terms of info index rather than set index to
avoid needless lookups. Add some new helpers to make this process
easier.
