LibWeb+LibWebView+WebContent: Add APIs to manage an autoplay allowlist
The spec defines a Permissions Policy to control some browser behaviors on a per-origin basis. Management of these permissions live in their own spec: https://w3c.github.io/webappsec-permissions-policy/ This implements a somewhat ad-hoc Permissions Policy for autoplaying media elements. We will need to implement the entire policy spec for this to be more general.
