winex11: Simplify the cursor clipping retry mechanism.
If the focus changes between Wine windows, the wineserver logic will decide to reset the clipping rectangle. However winex11 also needs to support the case when focus changes to a host window, in virtual desktop mode, and in this case the foreground window doesn't actually change.
To fix this, in virtual desktop mode, release the cursor on focus out events, and reapply the cursor clipping rect when the virtual desktop window is focused again.
We can use the same logic on NotifyGrab events, when the WM grabs the keyboard, and later reapply the Wine clipping rect when we are notified about the keyboard ungrab.
