  Message : Add ANGLE platform implementation template. The platform implementation allows the app layer to pass in an object, on which ANGLE can call virtual methods. Our current platform will handle trace events, for app profiling, and histogram records for statistics. The platform approach gives a much more robust approach than using entry points for every piece of functionality, and is based on the interop with Blink. The default platform implementation does a no-op on every call. The destructor is also private, to ensure we do not call the destructor of the passed-in class.
