Remove UserScroll from SmoothScrollSequencer.

Previously, we put all LayoutObject::ScrollRectToVisible into
SmoothScrollSequencer and use ProgrammaticScroll whenever we pop a scroll from
the sequence. However, some scrolls should be called with UserScroll instead of
ProgrammaticScroll, because we don't want scrollers with overflow::hidden to
scroll in some cases.

In this patch, we only put ProgrammaticScroll into SmoothScrollSequencer so
that UserScrolls can still be called with the correct parameters.

[Auto-generated comment by a script] We noticed that this issue is targeted for M-61; it appears the fix may have landed after branch point, meaning a merge might be required. Please confirm if a merge is required here - if so add Merge-Request-61 label, otherwise remove Merge-TBD label. Thanks.

Tested the issue using #62 .0.3196.0 on Win 7, Linux Ubuntu 14.04 and Mac 10.12.6 as per the observations mentioned in comment #0. Observed both logo and link is seen on hitting ctrl+f for find box and search for "f" or "ch".

Remove UserScroll from SmoothScrollSequencer.

This patch directly works on branch 3163, as the bug is release-block-M61. We
previously have a patch
https://chromium-review.googlesource.com/c/chromium/src/+/627697 that fixes the
bug. However, that patch relies on some other commits that are not yet merged
to M61. So we create this patch in order to merge it to M61.
