Imporved CPU integration

- Change PGXP integration to use wrapper functions
- Use modified function lookup tables to call wrappers or default funnctions based on mode
- Implement wrappers for interpreter too, recompiler sometimes calls interpreter functions
- Add UI elements for selecting CPU modes
- Only call precision version of NCLIP in modes where there are not going to be stale vertices in GTE registers

- Added support for CP0 co-processor functions
- Improve support for CPU functions (still broken in many games)

- Improved debug output to show values for inputs before they're modified

GPU plugin
- Ignore stale vertices (occurs when CPU  mode no longer writes to memory)
- Add Cyan vertex colouring for stale vertices
