lc-dec: Add sf adaptive_luma_filter_skip

This patch introduces a speed feature 'adaptive_luma_filter_skip'
to reset filter levels of luma based on the minimum filter levels
of reference frames and pyramid level of current frame.
This logic applies only when luma and chroma filter levels of
current frame are below a threshold determined by its pyramid
level. The sf is not enabled of frame type is OVERLAY_UPDATE or
INTNL_OVERLAY_UPDATE.

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