Reduce the size of TplDepStats structure

The structure TplDepStats holds statistics related to TPL
at 16x16 block level. Size of the few variables present in
that structure can be reduced by avoiding the left shift
operation with TPL_DEP_COST_SCALE_LOG2. This CL, optimizes
the memory of these few varibales by delaying the left shift
operation from population stage to consumption stage.
