Allow or deny screen capture

If enabled or not configured (default), a Web page can use screen-share APIs (e.g., getDisplayMedia() or the Desktop Capture extension API) to prompt the user to select a tab, window or desktop to capture. When this policy is disabled, any calls to screen-share APIs will fail with an error; however this policy is not considered (and a site will be allowed to use screen-share APIs) if the site matches an origin pattern in any of the following policies: ScreenCaptureAllowedByOrigins, WindowCaptureAllowedByOrigins, TabCaptureAllowedByOrigins, SameOriginTabCaptureAllowedByOrigins.
