gallium: added draw_set_mrd() function to fix polygon offset
The Minimum Resolvable Depth factor depends on the driver and can't just
be computed from the number of Z buffer bits.
Glean's polygon offset test now passes with softpipe.
Still need to determine the MRD factor for other gallium drivers, if they use
the draw module's polygon offset stage...
