[Gap Decorations]: Resolve crash related to collapsed tracks
This CL addresses a bug involving collapsed tracks with grid gap
decorations during fragmentation. In crrev.com/c/7000980, we previously
skipped building gaps for ranges with collapsed tracks but did not
adjust the gap index-to-set structure accordingly. This CL ensures that
entries are not added for ranges without sets, which occurs when tracks
are collapsed.
