becb014d27 nir: treat per-view outputs as arrayed IO 
This is needed for implementing multiview in panvk, where the address
calculation for multiview outputs is not well-represented by lowering to
nir_intrinsic_store_output with a single offset.

The case where a variable is both per-view and per-{vertex,primitive} is
now unsupported. This would come up with drivers implementing
NV_mesh_shader or using nir_lower_multiview on geometry, tessellation,
or mesh shaders. No drivers currently do either of these. There was some
code that attempted to handle the nested per-view case by unwrapping
per-view/arrayed types twice, but it's unclear to what extent this
actually worked.

ANV and Turnip both rely on per-view outputs being assigned a unique
driver location for each view, so I've added on option to configure that
behavior rather than removing it.

2514999c9c nir: add nir_opt_vectorize_io, vectorizing lowered IO 
Since nir_opt_varyings requires scalar IO and thus all drivers have to
scalarize it, this gives the option to re-vectorize IO after that.
