We'll add this to the root descriptor set since moving the binding
to one of the bindless sets would be hard to do; we'd need to track
the binding index of each "bindless" binding for set updates etc.
In order to stay within the limit of 8 sets, we also cannot introduce
a separate set for UAV counters (currently there are 6 bindless sets,
the static sampler set, and the root descriptor set).

Greatly improves performance in various games that update or
copy a large number of descriptors per frame due to the high
overhead of pthread_mutex_{un}lock.

Logically split up descriptor pool allocation in three types:
- STATIC: Root descriptors and internal allocation.
- VOLATILE: For packed descriptor set which comes from heaps.
- IMMUTABLE_SAMPLER: For immutable samplers. This should be removed once
we start allocating sampler sets at sampler creation time.

For now this is enbaled based on device capabilities, but future changes
may require this to be disabled for certain root signatures.

Further changes will require a rework of how resource binding
works inside a command list, so for now, this is just a cleanup
that also removes some old code that is no longer needed.

Static samplers are embedded in the root signature, so we can create
a separate descriptor set layout and descriptor set which we only
need to rebind when the root signature itself changes.

invalidating previously bound root descriptors.

This needs a major rework as the current implementation has bugs,
is hard to reason about, and very hard to maintain as we're about

Resource index is found in idx[0] in SM 5.0, but idx[1] when using SM
5.1, and register space is encoded separately. An rb_tree keeps track of
the internal resource index idx[0] and can map that to space/binding as
required when emitting SPIR-V.
For this to work, we must also make UAV counters register space aware.
In earlier implementation, UAV counter mask was assumed to correlate 1:1
with register_index, which breaks on SM 5.1.

Greatly reduce VA allocations we have to make and makes returned VA more
sensible, and better matches returned VAs we see on native drivers.
D3D12 usage flags for buffers seem generic enough that there is no
obvious benefit to place smaller VkBuffers on top of VkDeviceMemory.
Ideally, physical_buffer_address is used here, but this works as a good
fallback if that path is added later.
With this patch and previous VA optimization, I'm observing a 2.0-2.5%
FPS uplift on SOTTR when CPU bound.

Addresses the following limitations of the previous implementation:
- Only R32_{UINT,TYPELESS} were supported for buffers.
- Clearing an image UAV did not behave correctly for images with non-UINT formats.
- Due to the use of transfer operations, extra memory barriers were needed.
If necessary, this will create a temporary view with a bit-compatible
UINT format for the resource in order to perform a bit-exact clear.
