Guided CNN restoration: signal unit size.

An index `unit_index` is signaled at frame level to select one of two
unit sizes:
- unit_index = 0 means unit_size = 256 for low-res and 512 for high-res.
- unit_index = 1 means unit_size = 512 for low-res and 1024 for high-res.

For RDO, a loop is added in encoder side function
`restore_cnn_quadtree_encode_img_tflite_highbd` to pick the best unit
size.
