rsx: Workaround for G8B8 render targets

Browse source 
- Mainly affected are colormasks and read swizzles

NOTES:
- Writes to G write to the second and fourth component (YW)
- Writes to B write to first and third component (XZ)
- This means the actual format layout is BGBG (RGBA) making RG mapping actually GR
- Clear does not seem to have any intended effect on this format (TLOU)
