Add: Debug tool to draw widget outlines. (#11401)

This is considered a developer tool and is controlled from the help menu (or default hotkey Ctrl-O).

This draws a white dashed outline around widgets. NWidgetSpacer and (unused) WWT_EMPTY widgets are also filled with check pattern to highlight them, as they usually indicate a design issue.
