  Add abstractions for instantiating remote frame trees in iframe processes
https://bugs.webkit.org/show_bug.cgi?id=253482

Reviewed by Chris Dumez and Per Arne Vollan.

This PR does three things, all of which are useful when instantiating remote frame trees.

1. Instead of passing a FrameLoaderClient in the PageConfiguration, pass either a FrameLoaderClient
for a LocalFrame as the main frame, or a RemoteFrameClient for a RemoteFrame as the main frame.
2. Also pass a FrameIdentifier in all cases, which moves the logic about where it comes from
to the WebPage constructor (or to WebView.mm for WebKitLegacy).
3. Gather and send a FrameCreationParameters object with WebPageCreationParameters when setting up
a ProvisionalFrameProxy.  It currently only contains FrameIdentifiers in a frame tree and is unused,
but will soon contain more info like security origins and be used to construct the whole frame tree
in iframe processes.
