Window Placement: Prototype Fullscreen Capability Delegation - Part 2

This completes the prototype started in https://crrev.com/c/3575071

Support Fullscreen Capability Delegation when a flag is enabled:
--enable-blink-features=CapabilityDelegationFullscreenRequest
Frames can delegate via messaging another frame on activation:

• w.postMessage("m", { targetOrigin: "*", delegate: "fullscreen" });
  Another frame can use the delegated capability on message receipt:
• window.onmessage = () => { e.requestFullscreen(); }

Activate a browser-side FullscreenRequestToken in:

• RFHI::PostMessageEvent for RemoteFrameHost's RouteMessageEvent
• new RFHI::LocalMessageNotification for LocalFrameHost local messages

Focus windows using delegation to request fullscreen, so:

• user can press [Esc] to exit fullscreen
• another focused window doesn't z-order above/below fullscreen

Add automated tests supporting feature flag and local/remote usage
