[Site Isolation] `imported/w3c/web-platform-tests/storage-access-api/requestStorageAccess-web-socket.sub.https.window.html` fails

Reviewed by Sihui Liu.

WebSocketChannel was accessing the local main frame's document loader to read allowPrivacyProxy,
which doesn't work with site isolation when the main frame is remote. Add allowPrivacyProxy as a
virtual method on Frame, propagate it through WebsitePoliciesData to RemoteFrame, and change
WebSocketChannel::connect to access the frame tree in a way that works with site isolation.
