Compacts ranges and only issues one bind for buffer ranges and
full subresource updates, rather than one bind per tile.

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.

We might have to emit to different bind point than our binding entry
suggests due to DXR, so pass down information explicitly to leaf
functions.

Refactor push constant invalidation to SetPipelineState,
it is technically more correct to only invalidate when actually pushing
constants, but we need to do full state invalidation when transitioning
between RT pipelines and non-RT pipelines due to bind point aliasing
shenanigans in D3D12, so it makes more sense to invalidate state based
on active bind point there.

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.

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.

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

Fixes a validation error. With VK_QUERY_RESULT_64_BIT we need
to use 8-byte alignment, but ssbo_alignment may be less.

No longer requires BDA support since it's easier now to work
around buffer alignment issues.

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

We currently never reset occlusion queries. For some reason,
validation layers do not report this.

By resetting query pools in advance, we can reduce the number of
stalls between draw calls in passes with occlusion queries, which
is currently causing serious performance issues in some games.

Since we'll be inserting lots of single queries, we want to
avoid having to resize the range array since that is an O(n)
operation at worst.
