This allows mediump inputs and outputs to be trivially lowered into packed
16-bit varyings where 1 slot is occupied by 2 16-bit vec4s, without any
packing instructions in NIR and without any conflicts with 32-bit varyings.
The only thing that is changed is IO semantics in intrinsics to get packed
16-bit varyings.
This simplifies supporting 16-bit types for drivers that have 32-bit slots
everywhere except the fragment shader where they can do 16-bit interpolation
on either the low or high half of each slot.

There's reuse of values depending on the stage, so a function that
just takes the value might produce invalid results. All the codebase
was already changed to use the gl_varying_slot_name_for_stage()

If we were desperate to reduce bits, we could probably also use
shader_in/out for hit attributes as they really are an output from
intersection shaders and read-only in any-hit and closest-hit shaders.
However, other passes such as nir_gether_info like to assume that
anything with nir_var_shader_in/out is indexed using vec4 locations for
interface matching. It's easier to just add a new variable mode.

New intrinsics are added for global invocation IDs and work group IDs to
deal with offsets in both. The only one of these that needs a system value
is global invocation offset, for CL's get_global_offset().
Note that CL requires very large work group sizes, so these intrinsics
are modified to be able to use 64bit values, for 64bit SPIR-V.

We can remove a bunch of conditional code at key comparison time by
computing a bitmask of used key bits at ir3_shader creation time. This
also gives us a nice place to put additional key simplification to reduce
how many variants we create (like skipping rastflat if we don't read
colors in the FS, or skipping vclamp_color if we don't write colors).
It does mean walking the whole key to AND it, but the key is just 28 bytes
so far so that seems pretty fine.
