sw content controls, dropdown: add insert UI

- introduce a SwContentControlListItem::ToString() that tries to use the
display text of the list item, otherwise falls back to its value and use it
while building the dropdown widget and when inserting selected list item

- handle the dropdown case in SwWrtShell::InsertContentControl()

- expose this as a new .uno:InsertDropdownContentControl command

- mention the new and all previous content control commands in the
MS-compatible forms menu as well
