Now that we have the descriptor buffer mechanism, emulated texture
swizzle can be implemented in a very non-invasive way. Previous
attempts all tried to extend the push constant based image param
mechanism which was gross. This could, in theory, be done much faster
with a magic back-end instruction which does indirect MOVs but Vulkan on
IVB is already so slow this isn't going to matter much.

In 105002bd2d, we fixed a memory leak bug where we weren't properly
destroying descriptor when destroying/resetting a descriptor pool.
However, the only real leak that happened was that we we take a
reference to the descriptor set layout in the descriptor set and we
weren't dropping our reference. Everything else in the descriptor set
is tied to the pool itself and doesn't need to be freed on a per-set
basis. This commit changes the destroy/reset functions to only bother
walking the list of sets to unref the layouts and otherwise we just
assume that the whole-pool destroy/reset takes care of the rest.
Now that we're doing more non-trivial things with descriptor sets such
as allocating things with util_vma_heap, per-set destruction is starting
to show up on perf traces. This takes reset back to where it's supposed
to be as a cheap whole-pool operation.

In c520f4dec9, we chose to align the sizes of descriptor set buffers to
32 bytes. We have to align the descriptor set buffer to 32B so that
it's valid for using with push constants. We align the size as well so
we don't leave lots of holes with util_vma_heap_alloc. Unfortunately,
we were only aligning it for alloc and not for free so we were still
creating piles of holes when we delete descriptor sets. This causes
terrible perf for the allocator once we've deleted piles of descriptor
sets.
This commit reworks the code so that we align the descriptor set buffer
size to 32B for both alloc and free. The result is that it takes the
new crucible vkResetDescriptorPool from 104.567719 to 2.898354 seconds.

Previously, we were storing the per-binding create info pointer in the

Because we want to leave immutable_samplers as NULL for undefined

This commit adds a new way for ANV to do SSBO bindings by just passing a
GPU address in through the descriptor buffer and using the A64 messages
to access the GPU address directly. This means that our variable
pointers are now "real" pointers instead of a vec2(BTI, offset) pair.
This carries a few of advantages:
1. It lets us support a virtually unbounded number of SSBO bindings.
2. It lets us implement VK_KHR_shader_atomic_int64 which we couldn't
implement before because those atomic messages are only available
in the bindless A64 form.
3. It's way better than messing around with bindless handles for SSBOs
which is the only other option for VK_EXT_descriptor_indexing.
4. It's more future looking, maybe? At the least, this is what NVIDIA
does (they don't have binding based SSBOs at all). This doesn't a
priori mean it's better, it just means it's probably not terrible.
The big disadvantage, of course, is that we have to start doing our own
bounds checking for robustBufferAccess again have to push in dynamic
offsets.

This is really where they belong; not push constants. The one downside
here is that we can't push them anymore for compute shaders. However,

The descriptor set layout code in our driver has undergone many changes
over the years. Some of the fields which were once essential are now
useless or nearly so. The has_dynamic_offsets field was completely
unused accept for the code to set and hash it. The per-stage indices
were only being used to determine if a particular binding had images,
samplers, etc. The fact that it's per-stage also doesn't matter because
that binding should never be accessed by a shader of the wrong stage.
This commit deletes a pile of cruft and replaces it all with a
descriptive bitfield which states what a particular descriptor contains.
This merely describes the data available and doesn't necessarily dictate
how it will be lowered in anv_nir_apply_pipeline_layout.
