tu: Remove tu_shader_compile_options

The only two fields were always true, and I don't think we'd ever have
use for them. If we want to disable optimizations then we'd need a
different approach, and I don't even know what include_binning_pass was
for.

tu: Use the ir3 shader API

This will be necessary once we start compiling multiple variants due to
different const size limits, and it will also be necessary for properly
implementing the pipeline cache.

ir3: Pass reserved_user_consts to ir3_shader_from_nir()

ir3_shader_from_nir() calls ir3_optimize_nir(), which currently sets up
the const state. However, we need to know the number of user consts
reserved by the driver before setting up the const state, which means
that this information needs to be passed into ir3_shader_from_nir()
somehow rather than being set in the shader.

glsl: fix uniform array resizing in the nir linker

The initial support tried to match uniform variables from different
shaders based on the variables pointer. This will obviously never
work, instead here we use the variables name whcih also means we
must disable this optimisation for spirv.

Using the base variable name works because when collecting uniform
references we never iterate past the first array dimension, and
only support resizing 1D arrays (we also don't support resizing
arrays inside structs).

We also drop the resized bool as we can't skip processing the var
just because is was resized in another shader, we must resize
the var in all shaders.
