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.

Supported on: At least Microsoft Windows 7 or Windows Server 2008 family
