GeometryShaderGen: Use lower-left origin for point texture coordinates

From what I can tell, the emulated GPU places (0,0) at the lower left of
the image, and we were generating texture coordinates so that (0,0) was
at the upper-left in the expansion geometry shader, causing textures
used by point sprites to be flipped vertically.

Fixes the upside-down A button in Mario Golf.
