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).

Also stores the type ID of the pointer to the UAV counter struct,
since we need to load the pointer before we can access the counter.

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.

Allows us to have bindless UAVs without a special code path
for bindless UAV counters for now.

All attachments must be at least as large as the framebuffer, using a
max operator is not compliant with Vulkan.

NVIDIA currently seems to have some issues with bindless CBV on Vulkan,
which have been reported. Somehow, bindless SSBO works around black
screen on SotTR, as well as some rendering glitches on Control.
AMD won't care since UBOs and SSBOs are basically the same thing.

This method is meant to process d3d12 device caps after the
device itself has been fully initialized. This helps avoid
code duplication in certain instances and guarantees that we
know about all enabled Vulkan features.

Meant to bundle all d3d12 feature caps and options, of which
we're going to have to add more over time.

Used as a fallback for older Nvidia generations which do not
support bindless uniform buffers.

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.

Enables us to unroll root constant buffers. Not loading unneeded
components early may also help some drivers generate better code.

Having a lot of special code here just makes it harder for
us to implement UBO-specific load path, not to mention that
the mov instruction itself is very rare.
