Refine txfm domain dist speed feature for speeds 1,2

Introduced txfm domain distortion logic for boosted
frames in speed presets 1,2.

For speed = 1 and 2 presets, BD-rate impact is seen
as 0.03% and 0.05% (as per AWCY runs), with encode time
reduction of 4.85% and 4.72% (averaged across multiple
test cases) respectively.
