Reduce transform options for ext-tx experiment

Browse Source 
Reduces the transform optons for INTRA as well as INTER when
transform size is 16x16 to not use any of the DSTs.
Thus, a total of 10 options are used for 16x16, while 4x4
and 8x8 still uses 17 options.

derflr/hevchd actually improves a little, while hevcmr drops
a little.

About 10% speed improvement.
