Bug 1896516 Part 3 - Change GetScrollTargetFrame() to return ScrollContainerFrame. r=layout-reviewers,emilio

Browse source 
Also, simplify some callers of `GetScrollTargetFrame()` to drop
`nsIScrollableFrame*` and unnecessary `do_QueryFrame`. We'll continue removing
more `nsIScrollableFrame*` in later parts.
