DGC IBs are considered external IBs because they aren't managed by
the winsys and the BO itself isn't really useful. Passing a VA instead
will help for future work.

This wasn't needed in practice because DGC NV is only enabled for
vkd3d-proton and it always uses the global BO list but better to add it
anyways.

This will prevent the dynamic loader to pick the wrong function once we
rename things to the proper API names.
In any case, this should have been done all along anyway.

Compiler can't know that array_size() of the offsets parameter in
textureGatherOffsets is (at most) 4, so use a MIN2() to make the limit
visible. Just adding an assert() gets ignored in Release builds.
This fixes the following warning in Release compilation:
```

Undefined Behaviour Sanitizer (UBSan) detected the following when
running testing `dEQP-VK.graphicsfuzz.cov-fold-negate-min-int-value`:
`negation of -2147483648 cannot be represented in type 'int'; cast to an unsigned type to negate this value to itself`
SPIR-V spec states that OpSNegate(0x80000000) has to return 0x80000000;
in our case, -2147483648 should be -2147483648.
While this is not causing any issue because compilers seem to be
behaving like that, it is still undefined behaviour, so it expects to be
this handled explicitly, which is the purpose of this commit.

This allows using CreateSamplerYcbcrConversion and DestroySamplerYcbcrConversion
from the common runtime and will be required for vk_sampler and for using the

vkd3d-proton always sets the acceleration structure size to be the
whole buffer size. Because of that, allocating read back buffers
for all acceleration structures causes a system with a finite amount
of RAM to OOM.
This is solved by allocating read back buffers on build where the
required size is known.

"Rewrite and remove" is a super common idiom in NIR passes. Let's add a helper
to make it more ergonomic.
More the point, I expect that /most/ of the time when a pass rewrites uses, they
also want to remove the parent instruction. The principle reason not to is
because it takes extra effort to add in the nir_instr_remove and nir_opt_dce
will clean up after you eventually, right? From a compile time perspective, it's
better to remove earlier to reduce the redundant processing between the pass and
the next DCE run. So ... we want to be doing *more* removes. From a UX
perspective - the way to nudge devs towards that is to make the
preferred "rewrite-and-remove" pattern more ergonomic than the "rewrite but
keep". That justifies the simple "replace" name rather than something silly like
"rewrite_uses_and_remove".
