Add inter mode rd fitting/estimating model

1) Put in a framework to estimate RD score from prediction error.
   We do online training for each frame whenever the data number
   is large enough. Only 4x4 block is applied with the framework.
2) This is still a draft. We will adjust the parameters to
   have better trade-off between the coding performance and the
   skip rate in the follow up CLs.
3) Put the previous data collection code under flag
   INTER_MODE_RD_STATS_DUMP
