Prevents the window contents from being captured by other apps.
On macOS it sets the NSWindow's sharingType to NSWindowSharingNone.
On Windows it calls SetWindowDisplayAffinity with `WDA_EXCLUDEFROMCAPTURE`.
On macOS it sets the NSWindow's [`sharingType`](https://developer.apple.com/documentation/appkit/nswindow/sharingtype-swift.property?language=objc) to [`NSWindowSharingNone`](https://developer.apple.com/documentation/appkit/nswindow/sharingtype-swift.enum/none?language=objc).
On Windows it calls [`SetWindowDisplayAffinity`](https://learn.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-setwindowdisplayaffinity) with `WDA_EXCLUDEFROMCAPTURE`.
For Windows 10 version 2004 and up the window will be removed from capture entirely,
older Windows versions behave as if `WDA_MONITOR` is applied capturing a black window.
