Feature request: API for screen sharing

There's currently no way to manage screen sharing as WebView2 manages everything itself. This presents a few security issues, so we'd like to be able.

1. To disable screen sharing programmatically.
2. Display custom (more prominent) indicator when screen sharing is active instead of the built-in indicator.
3. Pause/Stop any active screen sharing session programmatically.

These can be achieved in a couple ways:

• For 1. a new API call could be added to disable screen sharing or PermissionRequested event could be fired for screen sharing as well.
• For 2. a new event could be added which indicates which screen / window / tab is being shared.
• For 3. new API calls could be added.
