Enable Loop restoration with Wiener filter for speed 5 and 6

In the parent version, Loop restoration (i.e., Wiener and
Self-guided) is disabled for speed 5 and 6. This CL modifies
the sf 'disable_lr_filter' to enable Wiener Loop restoration
filter alone for speed 5 and 6. Also, introduced a speed
feature to disable refinement stage around wiener filter
coefficients as it does not have much impact on quality
w.r.t. speed.
