winemac: Actually switch Win32 focus away from a window that has lost Cocoa focus.

[Ken Thomases]

I had been figuring that, after a WINDOW_LOST_FOCUS event, either the process
would receive APP_DEACTIVATED or the focus was being switched to another
window within the process and so we'd get a WINDOW_GOT_FOCUS event.  Either
of those would switch the Win32 focus as necessary.  However, there are cases
where an app remains active even though all of its windows have lost focus.

A simple case is when the Spotlight menu has been pulled down and focus is in
its edit field.  Mac-native apps stop blinking their insertion point (caret)
but Wine apps didn't.  Now they do.

Another case is when all of an app's windows are minimized.
