Sooner or later we were going to need divergent codepaths in decode, and
it looks like now is the time. Add a `params` typedef and pass it
through all the decoder callbacks. This is an alias for
drm_asahi_params_global, but use a typedef so we can change that later
without changing dozens of instances.

If we have two 16-bit copies to/from adjacent 16-bit registers, we can instead
use a single 32-bit copy from the 32-bit register pair. Since 32-bit integer
arithmetic is (almost) as efficient as 16-bit on AGX, this (almost) doubles
performance of affected parallel copies.

All shaders affected for thread count are in pubg... by chance the allocation
before used fewer registers than the calculated register demand (I guess because
we're conservative with our vector handling) and so got lucky and got higher
thread count. That shader is also helped massively for instructions.
The halfreg change doesn't matter -- we're not actually increasing register
demand, we're just being more choosy about our registers.

We now emulate an infinitely large binding table with bindless, so the sky is

For sRGB render targets, we encode sRGB when writing pixels into the tilebuffer
(in the fragment shader), not when writing out the image. When we actually write
out the tilebuffer to the image, we don't use the PBE's sRGB conversion, we just
bind it as a UNORM 8 image and blit the pre-transformed pixels.
We're about to add real sRGB support for the PBE, so make this linearization
explicit.

Both textures and images share a unified indexing scheme in AGX. When binding
tables are used, they can be mapped to texture state registers. Otherwise, there
is bindless access available.
It would be nice to map OpenGL's binding table based textures and images to AGX
texture state registers 1:1. The problem is that OpenGL allows more combined
textures and images than we necessarily have texture state registers. So, we use
as many texture state registers as we can, and then we fallback on an internal
bindless scheme mapping an extended binding table.
Add and use a lowering pass to map all of the API-level texture/image indices to
either texture state registers or bindless handles as required.

Deserializing isn't expected to be much more expensive than cloning, and the
serialized NIR is *significantly* smaller. So store the serialized instead of
the deserialized, and deserialize on the fly.
This reduces a lot of noise in valgrind due to random crap alloc'd against the
NIR shader by lowering passes that now get properly freed.

In general, PBE descriptors map pipe_image_views for the hardware. That we use a
writeable shader image internally for render targets is an implementation-detail
of the end-of-tile program. So, refactor the PBE upload routine to take a
pipe_image_view (not a pipe_surface), and translate the pipe_surface into an
internal pipe_image_view for end-of-tile programs.
