The first page load takes longer on WebKit2 because we have to wait for the WebProcess to launch.  Add API to launch it preemptively if we'd like.

This should call a function on WebContext that matches the suffix of the API function call and the logic should be in WebContext.

This isn't a good name for this.  How about WKContextWarmInitialProcess(...).  I also think this should go in WKContextPrivate.h
