Fixes the issue on winex11

As for the initial alt tabbing issue, somehow removing that hook call in win32u
as in the attached patch fixes the issue.
I'm not sure why winewayaland isn't affected, maybe it's because it doesn't
need to call NtUserSetForegroundWindow( NtUserGetDesktopWindow() ) in some
weird x11 cases when focusing out.
