Improve simple_motion_search_prune_rect

This commit turns on subpixel interpolation for simple_motion_search
features and adds in the partition bsize of left and top blocks as
features to the model.

There is a slight quality improvement and some speedup on speed 1.

Performance on Midres over 30 frames:
| AVG_PSNR | OVR_PSNR |   SSIM   | SPEEDUP |
| -0.0158% | -0.0186% | -0.0200% | +2.164% |

Quality is evaluated on the whole midres set without
sintel_trailer. Speedup is evaluated on five midres clips over 3
bitrates.
