Introduce weld::IconView::insert_separator
Needed to eventual re-implementation of starmath's SmElementsControl
using IconView.
This required re-implementation of IconViewImpl, to layout entries
by iteration, because now it's impossible to find an entry position
just based on its index.
This coincidentally fixed some visual glitches in non-gtk IconView
implementation from commit

icon view for RemoteFilesDialog
where any selected element could become first in row when scrolling.
SvTreeListBox::SetEntryHeight taking a SvTreeListEntry const* had to
be renamed to CalcEntryHeight, to avoid both virtual and non-virtual
overloads, additionally having different accessibility.
A TODO is implement separators in GtkInstanceIconView. I couldn't
find a GTK API for separators in IconView, so possibly a workaround
would be needed with some non-selectable narrow elements.
