i965: Mark needed downsamples for msaa winsys buffers
Add function intel_renderbuffer_set_needs_downsample. It is a no-op
except on multisample winsys buffers shared with DRI2.
Mark the needed downsamples with the new function at two locations:
- Immediately after drawing is complete.
- After blitting.
