LibWebView+WebContent+headless-browser: Make the page info IPCs async

Browse source 
The IPCs to request a page's text, layout tree, etc. are currently all
synchronous. This can result in a deadlock when WebContent also makes
a synchronous IPC call, as both ends will be waiting on each other.

This replaces the page info IPCs with a single, asynchronous IPC. This
new IPC is promise-based, much like our screenshot IPC.
