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.

For pipeline libraries and DXR to some extent later, we'll need an easy
way to compare root signature objects.

Similar issue with this as with NULL DSV rendering test. We did not test
the scenario where RTV is bound, then it is not bound anymore with same
PSO.

We did not test the scenario where we first render with depth enabled,
and then bind a NULL DSV with the same pipeline.
Also fix issues if we bind NULL RTVs with same pipeline bound.
Fixes crash in Guardians of the Galaxy.

This is benign and easily gets spammed a TON.
We will warn if an indexed draw is actually made like this.

UBSAN found a bug here since we store RTV descriptors inline, the
compiler can assume the pointer is 64 byte aligned.

If we're going to create different SPIR-V files from what the
VkPipelineCache represents, it's meaningless to load it.

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.

Wraps the D3D12 struct with a pipeline library handle.
This is needed if the blob contains references to external data,
which then needs to be resolved.

D3D12 expects drivers to implicitly synchronize transfer operations,
since there is no TRANSFER barrier ala UAV barriers.

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.

HZD issues an aliasing barrier for an alias of a resource that it
still needs.
Because D3D12 requires you to call DiscardResource or a full resource
clear/copy, we can just rely on those to do the actual image layout
transition and treat the aliasing barrier as a pure sync + flush.
This behavior is also observed in a test case where D3D12 drivers
do not seem to discard / fast-clear anything in an aliasing barrier.

Mesa RADV translates these legacy entrypoints to the 2 variants. Using
them directly will cost a bit less CPU cycles.
