Handle embedded DXIL subobjects and fix various issues exposed by the
upcoming new tests.
Associating with global root signatures, shader config and pipeline
config needs to be rewritten so that we validate uniqueness late.
The strategy here is to look at all exports we care about and find an
association.
There are many priority levels which are implied by how I understand the
DXR docs. State objects in the API win over embedded DXIL state objects.
Any DXIL state object wins over a collection.
Hit group associations can trump an entry point. It's not entirely clear
how this works, but we let it win if it has higher priority, i.e.
an explicit association directed at the hit group.
There's also cases where explicit assignment trumps explicit default
assignment, which then trumps just declaring a state object.
Collection state is inherited in some cases like AddToStateObject() even
if this seems to be undocumented behavior.

This is barely implementable, and relies on implementations to do kinda
what we want.
To make this work in practice, we need to allow two pipelines per state
object. One that is created with LIBRARY and one that can be bound. When
incrementing the PSO, we use the LIBRARY one.
It seems to be allowed to create a new library from an old library.
It is more convenient for us if we're allowed to do this, so do this
until we're forced to do otherwise.
DXR 1.1 requires that shader identifiers remain invariant for child
pipelines if the parent pipeline also have them.
Vulkan has no such guarantee, but we can speculate that it works and
validate that identifiers remain invariant. This seems to work fine on
NVIDIA at least ... It probably makes sense that it works for
implementations where pipeline libraries are compiled at that time.
The basic implementation of AddToStateObject() is to consider
the parent pipeline as a COLLECTION pipeline. This composes well and
avoids a lot of extra implementation cruft.
Also adds validation to ensure that COLLECTION global state matches with
other COLLECTION objects and the parent. We will also inherit global
state like root signatures, pipeline config, shader configs etc when
using AddToStateObject().
The tests pass on NVIDIA at least.

Docs explicitly specify that placed RTV / DSV resource must be properly
initialized before use, either on first use or after aliasing barriers,
so there should be no need to perform initial layout transition.
Fixes spurious GPU hangs in Hitman III where application aliases
an indirect buffer and a DSV. The DSV is cleared after the indirect
buffer is consumed, but the initial_layout_transition is triggered and
HTILE init clobbered the buffer.

Also be a bit more uniform with using break/return on fail conditions.
Otherwise, the indirect command will read data from the count buffer
instead, which may lead to bugs or GPU hangs.

Transfer batch can clobber graphics pipeline for e.g. depth->color copies.
Hence, flushing the batches after applying the graphics pipeline set by the
app can cause correctness issues.
To prevent that, do the transfer batch flush first before we apply any
render-related states.

offset_component_count was set to 0 for cubes, but GRAD path also
uses the variable to check how many components to use for GRAD.
OFFSET is not supported for cubes, so that's likely why it was bugged.

Separate scratch pools by their intended usage.
Allows e.g. preprocess buffers to be
allocated differently from normal buffers, which is necessary on
implementations that use special memory types to implement preprocess
buffers.
Potentially can also allow for separate pools for
host visible scratch memory down the line.

Scratch buffers are 1 MiB blocks which will end
up being suballocated. This was not intended and a fallout from the
earlier change where VA_SIZE was bumped to 2 MiB for Elden Ring.
Introduce a memory allocation flag INTERNAL_SCRATCH which disables
suballocation and VA map insert.

Also, be more robust against unsupported command signatures, since we
might need to draw/dispatch at an offset. Avoids hard GPU crashes.

Just use VK_NULL_HANDLE. We rely on the disk cache to exist anyways
here. We never serialize the global pipeline cache, so it might just
confuse drivers into disable disk cache if anything.
Also reduce memory bloat.
Also gets rid of very old NV driver workaround where we forced global
pipeline cache.

Transfer batches buffers CopyTextureRegion calls for batching.
The flushes needs to happen in a few places:
1. ResourceBarrier: This is where the transition from COPY_DEST to other
might happen, at which point the writes must be visible. This might
also transition away from COPY_SRC which invalidates the
precondition.
2. Copy operations. Copies to the same resource are implicitly ordered.
3. Draws and dispatches. These are not strictly necessary, but we don't
want too much command reordering so flushing here seems good.
4. Close. So that we don't throw commands into the void.
