Fix tree to cdf index mapping

This fixes the mis-aligned cdf model derived from tree based
model. It resolves the compression performance regression in
dual filter, intra mode, inter mode, and transform block type
coding, when ec-multisymbol is enabled by default.

With dual filter enabled, the performance regression was 3.6%
loss for lowres. This fix brings the performance gains back to 1%
gains.
