This commit introduces a new function nir_assign_linked_io_var_locations which is intended to help with assigning driver locations to shaders during linking, primarily aimed at the VS->TCS->TES->GS stages. It ensures that the linked shaders have the same driver locations, and it also packs these as close to each other as possible.
