Now that everything is using the new layout to emit descriptors we can
switch to the compact ABI. Even without mediump lowering this should
still offer increased performance for separate shaders, it also unifies
OpenGL and Vulkan code paths.

pan_cmdstream handles code common to both JM and CSF,
while valhall v9 didn't use CSF yet, they already used the
new version of the descriptor.
This lead to conditional compilation of various function with
similar names.
This commit renames some version-specific descriptor code to have
a versioned name, either `bi` (bifrost), `mid` (midfrost) or `val`
(valhall), to help with code comprehension.

Thewe new layouts actually take advantage of mediump to save on I/O
bandwidth, instead of focusing just on data types in the shader. Using
them requires that the driver use the varying layout for emitting any
needed varying descriptors.

If we're going to use the varying layout from the VS for the FS then we
need to be able to handle minor mismatches. Mostly, this just means we
need to drop the assert that the set of locations matches 1:1. We'll
use the byte offsets from the varying layout when we have one but keep
using the resource handles the driver put in driver_location for
LD_VAR[_IMM].

We want to flip the order in which we compile shaders and go in pipeline
stage order. In order to do that and continue to bake in noperspective
varyings, we need to scrape them out of the FS as a separate step.
Fortunately, that's now easy and safe to do.

We can easily handle indirect loads by looking at sem.num_slots.
Because noperspective is declared on the entire variable and not
individual slots of an array, we can smash noperspective on for the
whole range if we see an indirect. We also add collect from variables,
which is probably redundant when run late because variables are left
around after lowering I/O but it lets us run the pass before I/O is
lowered.

For the descriptor paths, we just assert that the locations match what
we expect and move on. For the direct paths, we use the offsets in the
layout. The compiler also now takes an optional layout which the driver
can provide itself if desired.

Right now, the varying layout is entirely a series of assumptions made
various places in the driver and compiler. This adds an explicit
structure for tracking the layout which we will eventually plumb through
everywhere.
