We only support the VariablePointersStorageBuffer feature for now,
which is the only one that is mandatory, and for which we seem to
be passing all the relevant tests already.
Exposing the optional VariablePointers feature would require that
we support non-constant indexing on UBO/SSBO first.
Relevant CTS tests:

This add a simple mechanism to select which GPU adapter the d3d12
driver should be using. A new environment variable is introduced.
MESA_D3D12_DEFAULT_ADAPTER_NAME
This represent a substring to search for in the GPU descrition,
for example "NVIDIA" or "INTEL", or "NVIDIA GeForce RTX 3090",
etc...
GPU are searched in order and the first one to include the substring
becomes a match. If no match is found, we default to the first
enumerated GPU.

No other drivers use the vendor in the title or path, so it seems better
to not do this for the vmware-guest driver as well. So let's rename it
to SVGA instead. The actual text itself makes it clear enough what it is
about.
This makes it stand out less in the toctree.
I chose the name "WMware SVGA3D", because that's less ambigious than the
"SVGA"-alternative, and was requested by VMware people.t

It seems something went wrong during conversion of this article (or
maybe even before in the HTML version), where every header after the
"Gallium environment variables" header was nested below it.
That's clearly not what's meant here, so let's fix that.
This makes the toctree make a bit more sense for this article.

This provides most of the implementation, but there are some
things we cannot enable until we improve of kernel submit
interface, namely:
We don't expose capacity to export SYNC_FD, although we do
have the implementation in place. This requires that we
improve our kernel interface and event wait implementation
first so we can cover the corner case where the application
submits a command buffer that includes a VkCmdWaitForEvents
and tries to export a SYNC_FD from its signal semaphores or
fence before it the event is signaled and the command buffer
is sent to the kernel for execution in full.
Likewise, we can't currently import semaphores. This is because
our current kernel submit interface can only take one syncobj.
We have been working around this so far by waiting on the last
syncobj produced from the device whenever we had to wait on any
semaphores (which is obviously suboptimal already), but this
won't work as soon as we allow importing external semaphores,
as those could (and would typically) be produced from a
different device.
Once we address the kernel bits, we should come back and enable
SYNC_FD exports as well as semaphore imports.

We don't have any special restrictions associated with the number
of descriptors in a set other than maybe not exceeding what we can
put in a single memory allocation, so in practice, applications will
be limited by the per-stage contraints defined by other Vulkan limits.

We don't do anything for input attachment aspects read by a subpass
since it doesn't have performance implications for us.
We also ignore the the new depth stencil layouts because they don't
have practical implications for our implementation.
We also ignore the new usage info for views since we are not currently
making decisions about views based on their usage.
