LibWebView: Create a spare WebContent process

Browse source 
Since cross-site navigation is a pretty frequent task, creating a spare
process is commonplace in other browsers to reduce the overhead of
directing the target site to a new process.

We store this process on the WebView application. If it is unavailable,
we queue a task to create it later.
