This is needed so that we can handle two special cases:
* Dynamic buffer data is allocated out of a command-buffer-owned buffer,
rather than a descriptor-set-owned buffer, so the remapping puts them
in their own register space.
* Static samplers should be left alone and not converted to bindless.

Rather than trying to perfectly defrag, let's just allow re-use.
When a set is allocated for the first time, it locks in its range of
the heap that it'll use. If the last set in the heap is used, then
those descriptors go back to being free, but if a set in the middle
of the heap is freed, those descriptors remain assigned to that set.
A later allocation attempt can reclaim them, as long as the new set
fits.

When operating in "bindless" mode, the device will own 2 descriptor
heaps, one for views, and one for samplers. Every time a view is
created (image view, buffer view), a slot is allocated for it out
of the device view heap for each usage type (sampled vs storage).
Then, in a future change, descriptor sets will just contain view/
sampler indices instead of actual descriptors. Instead of copying
these to a cmdbuf-owned descriptor heap, we can directly bind the
descriptor set as a buffer. We'll also modify shaders to perform
an indirection and index into the device heap.
Buffers also get views set up on creation. In a perfect world, we
could just put addresses/sizes in the descriptor set, but DXIL
doesn't support loading from addresses, we need descriptors. When
robust buffer access is disabled *or* descriptor set buffer views
reference the remainder of the buffer, we can just re-use a view
from the buffer and use an offset.

When running in a bindless mode, we won't ever be using SRVs for these.
Change terminology for determining descriptor offsets from "writable"
to "alt" to match naming already used elsewhere.

A future change is going to add descriptor heaps *to* the dzn_device,
and having 3x ID3D12Device pointers in a single object just seems
wrong. All of the callers already had a device, so just pass it
along where needed.

Only code that cares about Vulkan WSI should get the corresponding
arguments passed. Otherwise, the Vulkan headers might end up including
other headers that we don't have the correct dependencies passed for.
So let's give those a dedicated variable, and only pass that where it's
actually needed.

The shader key structure is quite large and memsetting it to zero to be
able to create or often simply find an existing shader is responsible
for a large portion of CPU usage during benchmarks.
This change is more surgical about what, when, and how things get
cleared.

Fixes 3DMark Wild Lands. Otherwise, we'd end up loading a DXIL shader
that had invalid linkage with another shader in the pipeline. We can
only load a DXIL shader if it's being linked against the same before
and after as a previous compilation.

This was a merge conflict from the Win32 WSI DXGI swapchain changes.
I missed moving a new line of code that was added when rearranging
things for using the common helpers.

Fix: Acquire/release should have one valid access/sync and one set
to none.
Workaround: D3D doesn't like simultaneous access resources leaving
COMMON layout, nor does it like setting UAV/RTV access bits for the
COMMON layout.
Use UNDEFINED -> UNDEFINED layout transitions, where the access bits
just aren't validated.
