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.
