gallium/radeon: separate DCC starts as disabled (ps_draw_ratio = 0)

DRI3:
- Only slows clears can enable it for the first frame.
- A good PS/draw ratio can enable it for other frames.

DRI2:
- Only slows clears can enable it for a frame.
- Page-flipped color buffers are unref'd at the end of each frame,
  so it can't be enabled in any other way.
- Relying on slow clears is sufficient for our synthetic benchmarks.
