Fix T72831: Incorrect animation handling when strips overlap

Function `SEQ_transform_seqbase_shuffle_time` did not have access to
strip effects, and therefore could not handle their animation. Since
now transformation knows what strips can't be directly moved, but their
position depends on other strips, this collection of strips is passed as
argument, so animation can be offset correctly.
