Query the signature of the traversal function stored in the any-hit
shader and make the parameter locations between the two match up, to
remove unnecessary movs inside the traversal loop.

Parameter assignment hints allow to influence parameter register
assignment logic with user-specified affinities. If there is an affinity
declared for a parameter, the assignment logic will try to match the
registers a parameter and its affinity are assigned.
It also allows to hint that certain registers are not suitable for
assigning parameters to and should be avoided.

We can express any-hit/intersection shaders as functions, too.
Any-hit/Intersection shaders need the usual parameters like launch
IDs/descriptor data/ray properties, origin, direction/etc., but also
some special parameters related to traversal state. Any-hit/intersection
shaders need to return whether the hit was accepted and/or traversal
should be terminated, as well as the intersection T value (for
intersection shaders). Both any-hit and intersection shaders also need
to be passed hit attributes via parameters. Closest-Hit shaders need
those too, but we pass them out-of-band via LDS. LDS is used for the
traversal stack when any-hit/intersection shaders, so we need to pass
them via parameters.
Hit attributes are similar to ray payloads in the sense that they're
dynamically sized depending on how much space the application uses.
However, unlike ray payloads, hit attribute sizes have a strict upper
bound of 8 dwords. To make managing parameters easier, we put all hit
attributes in a single vector parameter with 0-8 components. This
prevents having a function with two sets of arbitrary numbers of
parameters.
This commit sets up ahit/isec function signatures and implements
lowering for ahit/isec-specific intrinsics in the context of these
functions. Subsequent commits will merely have to call into these
functions to execute a separate-compiled any-hit/intersection shader.

terminate_ray should only return from any-hit shaders, it should not
skip the intersection shader. If we insert a nir_jump_return when
processing the already-inlined any-hit shader, the intersection shader
will be skipped.

comp-to-single is supported since GFX10, it's a new type of DCC fast
clear which doesn't require FCE and doesn't require to set fast clear
registers (ie. comp-to-reg). This means that it's possible to fast clear
even if not all slices are bound, because the clear code is stored in
the main image.
This improves performance in Dirt Rally 2.0 by +2-5%. Other games that
have layered clears would also benefit on GFX10+.

Like vkCmdClearAttachments(). This is a preliminary change for the
next commit which will enable these fast clears when comp-to-single
is supported.

Vulkan spec requires binding flags to be matched with the binding with
the same index, however currently bindings are sorted with flags not
properly sorted, which leads to bindings and flags mismatch.
Resolve this by adding optional flags info to the parameters of
vk_create_sorted_bindings(), and refactoring panvk/pvr (which really
pair bindings and flags instead of only iterating flags) to use sorted
flags.

This is possible because no comp-to-reg and no FCE. This probably helps
a bunch on GFX11+ if GENERAL is widely used with color images. And
since VK_KHR_unified_image_layout it's likely the case on GFX11-11.5
GFX10-10.3 could also benefit from this but some MSAA with DCC
fast-clears are currently broken and they need to be fixed first.

This allows us to skip the mode set by changing
