This removes setting _DrawVAO from all glDraw* functions that draw
primitives because now _DrawVAO is always equal to the current VAO.
glEnd, glRasterPos, and the slow display list path now have to save
_DrawVAO before changing it, and restore it after they are done.
This also removes _EmptyVAO, which becomes unused because we no longer
bind "no VAO" into _DrawVAO.
Rules:
- only glBindVertexArray and non-glDraw* paths should call
_mesa_set_draw_vao, other places shouldn't
- only draws should call _mesa_update_vao_state, other places shouldn't

Drivers implementing descriptor buffers will want to allocate and free
descriptors with the layout for embedded samplers, so we need a hook to
allow them to free any GPU buffers.

With descriptor buffers, we have no way to know how big the descriptor
set actually is, so we have no idea how many constants we can safely
push. If we use a UBO then it will still get pushed, because we normally
assume that we can freely access UBOs without any fear of faults due to
the range checking. This does the easiest thing of using raw pointer
loads, although performance will fall off a cliff, because we don't have
many better options.

The immediate offset is in units of bytes, whereas the register offset
is in dwords. We need to compensate for that.
Also, fix an off-by-one when checking the range - the offset field is 13
bits, but the sign bit means we can only represent up to 1 << 12 in
bytes or 1 << 10 in dwords.

All of the full runtime+compiler stacks reassign these driver_location
values to compact them and sort between shader stages, but for the
spirv2dxil tool, we leave the original shader's "location" intact. That
means that there can be holes in the driver_location space, and simply
counting how many inputs there are can lead to collisions. So instead
place all sysvals after the last-used driver_location.

FS inputs are not directly loaded into regs, but require additional
instruction to do so. So in order to print in which reg the input
is loaded we have to scan the shader for the instruction
which loads the input.

CSE tries to collapse equal instructions, and collapsing two phis with incompatible dests is illegal.

The previous check assumed the stack starts at offset=0, which isn't
necessarily true for ray queries.
Note that this didn't cause correctness issues, just made an optimization
not apply. Found when I accidentally made this load-bearing in a
refactor.

Instead of calling like this:
st_draw_gallium -> cso_draw_vbo -> driver_draw_vbo
Do it like this:
st_draw_gallium -> driver_draw_vbo
OR
st_draw_gallium -> u_vbuf_draw_vbo
It's accomplished by adding a draw_vbo function pointer into cso_context.
The pointer is equal to pipe_context::draw_vbo when needed, so there is
no call overhead from this if cso's draw_vbo callback is indeed equal to
driver_draw_vbo. We just call cso_context_base::draw_vbo to jump into
the driver directly, or u_vbuf if needed.
The cso function with the indirect function call is inlined, so draws
don't actually visit any cso_context function.

While the hardware supports both counter and boolean occlusion queries, the
programming model is quite different from OpenGL. In AGX (and in Metal),
there is a single "visibility result buffer" associated with the render pass.
Each draw that uses occlusion queries writes into this render pass global
visibility result buffer at a particular index. By contrast, the OpenGL
occlusion query model supposes that each query has independent state that can be
mixed and matched within a render pass. We can't simply allocate backing memory
for a query and write to it from a job. We can't allocate visibility result
buffers for each batch up front and statically assign OpenGL queries to indices,
because the OpenGL query can span multiple batches. Finally we can't use a
global visibility result buffer without introducing additional synchronization,
given that we now support multiple batches in-flight at once.
In this patch, I've elected to use a simple solution: allocate visibility result
buffers and indices on the fly as needed, and accumulate the results on the CPU
at the end of the render pass. When we have proper synchronization we'll want to
revisit this, but as everything is stalling at submit time now, I'm not inclined
to "optimize" something I can't test.
Passes dEQP-GLES3.functional.occlusion_query.* and the relevant piglit tests.
The piglits are considerably more thorough, checking lots of "we hate tilers"
conditions that dEQP skips over.

First remove agx_shader_key from asahi_shader_key. It's trivial. agx_shader_key
is going to go away soon now that we lower everything in NIR.
Then everything else is mutually exclusive between stages. That means much
less to hash. drawoverhead test 1 from 2331 to 3443.
