Make bit-stream support rectangular tx_size

This commit makes the encoding process of the recursive transform
block partition support both rectangular and square transform block
sizes as the starting point. If the coding block size is rectangular,
it would allow the transform block size to start from the largest
rectangular transform size, and recursive parse to the selected
coding sizes.
