compiler/nir_types: Handle vectors in glsl_get_array_element
Most of NIR doesn't allow doing array indexing on a vector (though it
does on a matrix). However, nir_lower_io handles it just fine and this
behavior is needed for shared variables in Vulkan. This commit makes
glsl_get_array_element do something sensible for vector types and makes
nir_validate happy with them.
