nir: Add per_view attribute to nir_variable
If a nir_variable is tagged with per_view, it must be an array with
size corresponding to the number of views. For slot-tracking, it is
considered to take just the slot for a single element -- drivers will
take care of expanding this appropriately.
This will be used to implement the ability of having per-view position
in a vertex shader in Intel platforms.
