Disable compound prediction in TPL for speed 1

The CL extends the TPL sf setting 'allow_compound_pred = 0'
from speed 2 to speed 1.

Encoder performance results averaged over all resolutions are
as follows:
   Instruction Count          BD-Rate Loss(%)
cpu   Reduction(%)   avg.psnr  ssim    vmaf   vmaf_neg  uvq_1p5
 1       3.371       -0.0988  0.1752  0.0371  -0.0065   0.1989

STATS_CHANGED for speed = 1
