winemac: Send WM_{ENTER, EXIT}SIZEMOVE around window frame changes initiated by Cocoa.

The Mac driver was already sending these events when the user resizes the
window by dragging its corner/edges, but there are other occasions when the
window frame changes.  For example, when the user zooms the window.
