st/mesa: Update shader info of ffvp/ARB_vp after translation to NIR
We must update stp->Base.info after translation and before
st_prepare_vertex_program is called, because inputs_read
may become outdated after NIR optimization passes.
For ffvp/ARB_vp inputs_read is populated based on declared
attributes without taking their usage into consideration.
When creating shader variants we expect that their inputs_read
would match the base ones for input mapping to work properly.
