Only search the largest tx_size for cbs above 64

If any dimension of a coding block size is above 64, only search
the largest transform block size, since the max transform block
size supported is 64x64.

Bring back this under a speed 1 feature. The encoding goes 2.5%
faster.

Stats change expected.
