Current TMuC uses MDDT for 4x4/8x8 and ROT for other sizes. It was suggested to allow two coding tools as it was proposed in CfP - MDDT for 4x4/8x8, ROT for all sizes. (It is easy since ROT is 2nd transform after any kind of first transform)

Configurability to allow testing this feature is useful to identify the validity of the unified design of TMuC.

It was suggested to add enabling/disabling the case of TU across PU. Since current TE12 plans to test both RQT=0/1, it is preferable to add this feature for both RQT=0/1.

(C.f. RQT=1 case, this feature is same to HHI_RQT_FORCE_SPLIT_ACC2_PU macro in 0.5-hhi branch. For RQT=0 case, it is a simple change on top of it.)

It was suggested to enabling/disabling PU partitions as:

• Enable/disable Inter 2NxN and Inter Nx2N
• Enable/disable Inter NxN
• Enable/disable Intra NxN

All changes should have syntax change, thus the first and second item may not be totally independent macros.
