rsx/interpreter: Improve instruction accuracy

Browse source 
- Fix DIV instruction
- Add EXP_TEX modifier
- Implement WPOS register read
- Swap 3D and Cubemap enums to match RSX ids
- Adds two extra instruction classes: flow control and packing control
- Implement remaining FP instructions with exception of the rare projected texture lookups
- Fix typo causing output color index > 0 to not work
- Fix KIL instruction
- Implement conditional vertex program writes
