glsl: keep track of intra-stage indices for atomics

This is more optimal as it means we no longer have to upload the same set
of ABO surfaces to all stages in the program.

This also fixes a bug where since commit c0cd5b var->data.binding was
being used as a replacement for atomic buffer index, but they don't have
to be the same value they just happened to end up the same when binding is 0.
