a4xx: add polygon offset clamp, fix units
For some reason, in order to get all tests to pass, pretty much all
hardware (across vendors) has to program in offset_units * 2. This fixes
dEQP-GLES3.functional.polygon_offset.float32_displacement_with_units.
While we're at it, add polygon offset clamp support.
