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.
The runtime changes are:

Use box with largest ray interval for shadow rays (terminate on first
hit) as it maximizes the probability of finding some object in that box;
for reflection (closest hit) rays, use midpoint instead, which defers
processing of larger boxes the ray origin is in in favor of smaller
boxes closer to origin.
Since the sorting mode must be uniform, when terminate_on_first_hit flag
is divergent, we leave it as closest.

Prior to VCN4, the encode queue is separate from the decode queue. For
encode, the WRITE_MEMORY command can be executed with similar framing as
for VCN4, but notably there is no signature support, so it must be
skipped.

The previous code not only left them undefined, but also
didn't increment the array index, so subsequent PS inputs
would be broken after the undefined one.
Note that this doesn't affect any valid Vulkan apps, but it makes
the code a bit simpler and it makes undefined inputs a little more
forgiving, at no expense for valid PS.
This code actually uncovers a bug in Zink, so I'm also documenting
the failing Zink test case.

There are some FS built-ins that can be per-vertex or
per-primitive depending on whether a mesh shader is used:
primitive ID (implicit in VS), layer and viewport.
However, the HW requires per-primitive FS inputs to be ordered last.
This causes bugs when the same unlinked FS is used together
with VS/TES/GS and MS (with unlinked ESO or fast-linked GPL).
To solve this problem, we reorder the FS inputs so that these
potentially per-primitive inputs go after per-vertex inputs but
before per-primitive inputs.

When debugging a game that compiles a ton of shaders at beginning, it
can be very very slow because shaders cache was disabled by default
with RADV_DEBUG=hang.
To make debugging such a game faster, let's cache shaders with
RADV_DEBUG=hang. Note that only the backend IR (ACO or LLVM) and the
disassembly are stored in the cache. To get SPIR-V and NIR, you might
need RADV_DEBUG=hang,nocache.
This also handles the trap handler.

This imports 35 libdrm_amdgpu functions into Mesa.
The following 15 functions are still in use:
amdgpu_bo_alloc
amdgpu_bo_cpu_map
amdgpu_bo_cpu_unmap
amdgpu_bo_export
amdgpu_bo_free
amdgpu_bo_import
amdgpu_create_bo_from_user_mem
amdgpu_device_deinitialize
amdgpu_device_get_fd
amdgpu_device_initialize
amdgpu_get_marketing_name
amdgpu_query_sw_info
amdgpu_va_get_start_addr
amdgpu_va_range_alloc
amdgpu_va_range_free
We can't import them because they make sure that we only use 1 VMID
per process shared by all APIs. (except the marketing name)

Create a CS which contains just a cache flush,
that can be used as a postamble in command submissions.
According to RadeonSI code, the kernel flushes L2
before shaders are finished on GFX6.
Previously, RADV always added a flush at the end of
each command buffer. The flush postamble should be
a less wasteful alternative to that.

This was just broken because individual shaders were still stored
on-disk in many situations:
- for shader object, all compute/graphics shaders were stored
- for fast-GPL, graphics shaders were stored
- for pipeline binaries, when the create flag was used
- for rt capture/replay and ray history
This should stop storing unused binaries on-disk and save space.
Found this by inspection.

The game aliases two images. It binds a memory object to two different
images, the first one being an image with 4 mips and the second with
only one mip but the bind offset is incorrect. It's like it queried
the first image size with different usage flags, so that DCC was
disabled.
Force disabling DCC for mips fixes the incorrect rendering and doesn't
hurt performance.

If nir_tcs_info::all_invocations_define_tess_levels is true, the pass
doesn't have to insert a barrier and use output loads to get tess level
output values. It can just use the SSA defs that are being stored (or phis
thereof) to get the tess level output values.
The remaining tcs_info fields will be used by the HS shader message.
