7301e92d49 vulkan/runtime/bvh: Propagate opaqueness information through the BVH
AMD hardware can early-cull box nodes if all leaves are either opaque or
not and the ray flags are set to discard (non-)opaque geometries. This
works even across TLAS/BLAS boundaries.

Propagate info on whether all child nodes are opaque or not through the
BVH to allow RADV to set these flags per box node.

4cbbdc0a50 vulkan: Pass a structure to most BVH build callbacks
It is annoying to change all function signatures when a driver needs
more information. There are also some callbacks that have a lot of
parameters and there have already been bugs related to that.

This patch tries to clean the interface by adding a struct that contains
all information that might be relevant for the driver and passing that
to most callbacks.

3141033ac2 vk/bvh: Add default stubs for unsupported entrypoints
We don't currently support building acceleration structures on the CPU
or indirect building in the common framework, and drivers using it don't
either, but drivers have to return non-NULL entrypoints for CPU building
functions if they claim to support VK_KHR_acceleration_structure. Add
stub entrypoints here so that drivers don't have to have this
boilerplate.

Fixes dEQP-VK.api.version_check.entry_points on turnip.

f8b584d6a5 vulkan/runtime,radv: Add shared BVH building framework
This is mostly adapted from radv's BVH building. This defines a common
"IR" for BVH trees, two algorithms for constructing it, and a callback
that the driver implements for encoding. The framework takes care of
parallelizing the different passes, so the driver just has to split the
encoding process into "stages" and implement just one part for each
stage.
