LibWebView: Add simple ID tracking to WebViews

Browse source 
For Firefox DevTools, we will need to track WebViews by a numerical ID.
Here, we just increment a static 64-bit counter. We can switch to using
IDAllocator if we ever have an issue with this.

This patch adds such an ID to the views and a couple of APIs to access
WebViews after creation.
