When the window manager moves windows offscreen, the Win32 config is explicitly kept out of sync. We need to handle that case when the Win32 config changes, to avoid forcefully moving the windows back on screen.

Since 895ca2eda64f506b936999cdd8f14e224eef6a7f the window position might be out of sync between Win32 and X if the X window manager has moved it offscreen.
Then b936f7426e33508538f48f7d20e7d7cb47cc1f32 ignored size and position changes, trying to avoid triggering requests that would force the X window position to match the Win32 state.
However, the X visible rect might change on window style adjustments, and not from a application-requested size change, and we need to request these changes to the X server.
The SWP flags should be handled in win32u already and the window rect position and size should not have changed if SWP_NOSIZE | SWP_NOMOVE were set by the application.
What we need to do is to mind that the X window position might be out of sync, and adjust the request to take the eventual offscreen position into account.
