We currently can't implement this in a meaningful way, but we
should return an empty blob in order to not crash applications.

We need a more extensible struct to contain the pipeline
descriptions in order to be able to support new rendering
features.

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).

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.

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.

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

Will be used on implementations that do not support enough
push constants to hold all root signature data.

We still need to pass binding info for each range to the shader compiler,
but bindless ranges will not contribute to the packed descriptor count.

Don't enable any bindless features for now so that we don't
introduce regressions as features get added.

Now that the binding code no longer makes any wild assumptions about
the exact binding layout, we can safely do this. Will make implementing
bindless a bit easier.

Uses the new data structures to iterate over descriptor
tables and populate the packed descriptor set.

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.

- descriptor_index is the index of the descriptor within the packed
descriptor set or root descriptor set. Currently unused.
- binding_index should now index into the root_signature->bindings array.
- vk_set and vk_binding refer to the Vulkan descriptor set index and
binding number of packed descriptors or root descriptors.

Allows us to more easily refactor root signature-related code
without having to worry about root descriptors for now.
