Browser Plugin: Change internal API to track V8 object lifetime

This is the first step towards moving the permission API and New Window API
out of content and into chrome.

This CL decouples v8 object lifetime tracking from the permission API.
In particular, when a tracked object goes away an -internal-trackedObjectGone
event fires that allows the content embedder to do any necessary cleanup, if
necessary such as deny the permission request in the case of the permission
API

BUG=166165
Test=WebViewTest.GeolocationRequestGone
