The runtime is specified to validate certain things.
Also, be more robust against unsupported command signatures, since we
might need to draw/dispatch at an offset. Avoids hard GPU crashes.

Useful when used together with pipeline library logging. Confirms that
we can load pipeline caches as expected.

Additionally, add option to ignore cached SPIR-V.
Will be useful for debugging, and also required for VKD3D_SHADER_OVERRIDE.

Avoids saving out pipeline cache blobs which are likely going to be
cached by on-disk cache anyways.

This key represents the variations of SPIR-V which would be generated
from otherwise identical inputs like DXBC blobs and root signatures.
Typically, changing VKD3D_CONFIG flags or enabled extensions will affect
this key. This ensures that we will not attempt to use a cached SPIR-V
file unless we can trust that the SPIR-V interface will match.

In DEATHLOOP, there is a render pass which renders out a simple image,
which is then directly followed by a compute dispatch, reading that
image. The image is still in RENDER_TARGET state, and color buffers are
*not* flushed properly on at least RADV, manifesting as a very
distracting glitch pattern. This is a game bug, but for the time being,
we have to workaround it, *sigh*.
For a simple workaround, we can detect patterns where we see these
events in succession:
- Color RT is started
- StateBefore == RENDER_TARGET is not observed
- Dispatch()
In particular, when entering the options menu, highly distracting
glitches are observed in the background.

The creation with those extensions may fail in few cases:
* older 32 bit drivers
* missing or inaccessible /dev/nvidia-uvm
There's also a mysterious crash that some Debian users experience with
64bit titles and a correct /dev/nvidia-uvm.

Halo Infinite uses &desc->Width for total_bytes.
We can't set total_bytes early because code after this relies on desc->Width.

The 16-byte requirement is kind of a lie. The real requirement is tied
to how vectorized load-store instructions are emitted in the shader
itself since I guess it allows compiler to assume something about
alignment of the base pointer.

The Vulkan spec update 1.2.195 restricted these features to a very limited
format subset, and somehow this is supposed to not be an API break?
Anyway, let's follow the new rules.

It's common enough that new games break on RDNA2 because of this that we
should enable this by default. This matches DXVK behavior.
SOTTR gets a special weird exception, just like DXVK. The shaders are
broken enough that the proper fix is actually precise, not invariant.
This will be addressed at some later point.

Useful for test suite since a test can be comprised of several smaller
submissions, and it's easier to debug if we have one trace.

Many UE4 games have this broken bloom shader that samples a texture with implicit lod in divergent control flow.
