i965: Generalize brw_vec4_upload_binding_table() beyond vec4 stages.

Instead of passing in a brw_vec4_prog_data structure, we can simply
pass the one field it needs: the number of entries in the binding table.

We also need to pass in the shader time surface index rather than
hardcoding SURF_INDEX_VEC4_SHADER_TIME.

Since the resulting function is stage-agnostic, this patch removes
"vec4_" from the name.
