lc-dec: Tune sf adaptive_luma_loop_filter_skip

In this patch, the speed feature 'adaptive_luma_loop_filter_skip'
is tuned by setting 'filter_threshold'=16 for 'pyramid_level'=5 and 6.
This change improves the visual quality for low complexity decode
mode.

Performance results of encoder and decoder for the streams generated
with low complexity decode mode enabled.
