Idea is to keep track of scenarios where we know a resource's aspect is
known to be in a OPTIMAL state. Based on this, we can override the image
layout from the common_layout in order to avoid unnecessary full
barriers.

For copies, we can always use the intended aspects, since we have
separate DS layouts now.

When clearing a DSV, we must get aliasing guarantees, so we must
transition away from UNDEFINED. This is only possible when using
separate_ds_layouts and for render pass clears we need to use
renderpass2 mechanisms to do this.

GravityBench ends up using ClearView with too large dimensions.
This is a validation error in Vulkan, so just clamp the extents.
To make full rect detection a bit more robust, do a range check instead
of memcmp().

If we're doing a layout transition of depth-stencil aspects, we need to ensure all potential
accesses are made visible.

- Honor resource barriers for resource states which cannot automatically
decay or promote. This includes COLOR_ATTACHMENT, UNORDERED_ACCESS and
VRS image. If SIMULTANEOUS_ACCESS is used, we can still promote, and
we handle that by setting common layout to GENERAL for these resources.
- Avoid redundant barriers in render passes since normal resource
barriers will always make sure we are already in
COLOR_ATTACHMENT_OPTIMAL.
- Do not force GENERAL layout if resource has UNORDERED_ACCESS flag set.
As this is not a promotable state, we have to explicitly transition
into it. I tested this on validation layers, where even COMMON state
refuses to promote to UAV state. The exception here of course is
SIMULTANOUS_ACCESS, but we handle that properly now.
- Verify that UAV or SIMULTANEOUS access is not used together with DSV
state. This is explicitly banned in the API docs.
- Actually emit image barriers. Batch the image transitions as that's
what D3D12 docs encourage app developers to do, and it also expects
that drivers can optimize this. Ensure that we respect the in-order
resource barrier rules by splitting batches if there are overlaps in
the transitions.
- Ensure that correct image layout is used when clearing a suspended
render pass attachment.

Avoid using the separate layouts if we're only using formats with one
aspects. This makes it more likely to match layouts with common layout,
and we can avoid awkward transition barriers.

Fixes test TODOs. Apparently Vulkan drivers can saturate here, which
caused the TODO to appear, at least on AMD Windows.

Needed so we can switch between having a VRS and non-VRS attachment on the fly.
Extensible enough for this to work for other things down the line also.

There isn't much of a reason why we should have to do this. The original

Increment physical value one by one, find the exact timeline value we're
supposed to signal and perform the update.
Select lowest physical timeline value correctly.
Array can be reordered now, so lowest value isn't necessarily first.

Rather than one per device. This solves issues with D3D12 fences
being signalled too late because the fence worker is waiting on
a different set of semaphores while the fence is being enqueued.
Greatly increases performance in Horizon Zero Dawn and Death
Stranding with multi-queue mode enabled.

This will be necessary once we introduce fence workers per

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.
