oox: mso-wrap-style is about wrapping mode for text in shapes

This commit partially reverts 9e8957de203bb9abb208516ad32aee9527feb67b
(as it interpreted mso-wrap-style as the wrap type of the textbox
itself, not the wrap type of the contained text) and also extends the
effect of commit 0016757efef898205452a586ba5927e5d11fdabe to the
SimpleShape class as well.
