sw content controls: add overlay to render a border around the text portions

- introduce SwSelPaintRects::HighlightContentControl() to create the
overlay

- use GetTextAttrAt() to enable this when we're inside a content control
(not only when the cursor is exactly at the dummy char of the content
control, which is at the start)

- tested that this works correctly even if the portions inside the
content control don't have the same height (similar to the selection
overlay)
