Rewrite intra prediction mode coding to be simpler.
...
Should work exactly the same, but with the prediction mode selection done
separately from the binarization it's easier to see that the implementation
is correct.

- Monochrome coding was removed as it's not part of the standard.
- No other functional changes.

LCU at a time.
