richedit: Tests for visibility behavior of richedit scrollbars, with todo_wine.

Some applications have never heard of ES_DISABLENOSCROLL and attempt to force scrollbars to be always shown (with ShowScrollBar() or similar) when otherwise richedit would hide them. If richedit attempts to wrestle control back, a recursive loop of requests can result if app overrides WM_SIZE behavior. Apparently native never reads the scrollbar state, and operates from some sort of internal state, so that scrollbars can be modified externally without native trying to wrestle back control. This is confirmed by attached tests. An exception: EM_SCROLL will restore visibility to a scrollbar that was forcibly hidden.

hide the vertical scrollbar) and are thrown on an endless recursive loop
