Fix depth buffer issue causing translucent sprites to not render properly in Polymost.

Browse source 
Use polymost_spriteHasTranslucency() and polymost_maskWallHasTranslucency() to determine if a sprite has translucency.
Optimize sprite rendering when in Polymost by only sorting sprites with translucency.
