glamor_putimage: Optimize for direct uploading and fallback path. 

This commit optimize two cases:
1. When the clip contains the whole area, we can directly upload
the texel data to the pixmap, and don't need to do one extra
clipped copy.

2. At fallback path, we don't read back the whole pixmap, just
need a sub region.
