Timothy Arceri e5301cfeef glsl: fix slow linking of uniforms in the nir linker
Currently the nir linker resizes the amount of storage needed to hold
uniform information on the fly while linking. As shaders can contain
thousands of uniforms this can be very slow. For example some Godot
shaders can take 30 seconds to compile on some machines.

In this change we count the amount of storage needed before we start
processing the uniforms. This is what the GLSL IR linker does also.

Fixes: 95f555a93a ("st/glsl_to_nir: make use of nir linker for linking uniforms")
Closes: https://gitlab.freedesktop.org/mesa/mesa/-/issues/2996
