Remove old unnecessary functions from search module.
...
- As we move to per-LCU encoding only search_lcu will be necessary.
- Function search_best_mode is no longer used.

Set correct max depth for search work-tree copying.

4x4 blocks.

Tuned cost calculations for "final cost"
...
By adding chroma cost and using 1.5x coeff cost instead of 0.5x, additional 3% (LP) and 1.8% (AI) drop in BD-rate noticed.

Try and get NxN to work again.
...
- Moved NxN search to be done on the same level as other searches, as it's
really not any different from 2Nx2N.
- Produces working bitstream but reconstruction is different.
