radv: move lower_io_arrays_to_elements before lower_io_to_scalar_early
nir_lower_io_arrays_to_elements lowers arrays or matrices to elements,
which ends up to vectors for matrices, but a bunch of IO optimizations
only work for scalars.
Calling it before lower_io_to_scalar_early allows nir_link_opt_varyings
to remove duplicated inputs and replace constant inputs.
