Selection API of INPUT/TEXTAREA should not update FrameSelection without focusing.
We had an option SelectionOption::ChangeSelection, which updates FrameSelection
regardless of focus state. It's harmful because it caused focus-FrameSelection
mismatch. We don't need such option, and ChangeSelectionIfFocused should be the
default.
This CL needs to update many layout tests because they assumed
setSelectionRange() updated FrameSelection.
