Retrain simple_motion_search_based_split on speed 1-2

The model is retrained using simple_motion_search results from
PARTITION_NONE and PARTITION_SPLIT without two_pass_partition_search.

The new model is only enabled on lowres and midres, where
there is significan speed up. The model's thresholds can be further
refined on lowres. On hdres, the performance is fairly neutral, but we
might get gains if we disable two pass partition search

Performance:
 TESTSET | AVG_PSNR | OVR_PSNR |   SSIM   | AVG_SPDUP | OVR_SPDUP |
  MIDRES |  -0.127% |  -0.141% | -0.213%  |  +8.202%  |  +9.012%  |
  LOWRES |  +0.075% |  +0.080% | +0.038%  |  +8.468%  | +10.568%  |
