etnaviv: vectorise io

Browse source 
This etnaviv backend code depends heavly on optimisation passes eliminating
all but a single write to shader outputs. Here we make sure that shader
output writes are vectorised.

Fixes: 7647023f3b ("glsl: enable the use of the nir based varying linker")
Closes: https://gitlab.freedesktop.org/mesa/mesa/-/issues/6536
