Subject: [Android] Implement renderer side of Gin Java Bridge
This change adds GinJavaBridgeObject and GinJavaBridgeDispatcher classes.
GinJavaBridgeDispatcher is a per-RenderFrame manager of injected
objects. It interacts with the browser side.
GinJavaBridgeObject is a Gin-based wrapper injected into page's context
that exposes methods of the corresponding Java object and receives
method invocation requests from JavaScript.
