Truffle/Instrumentation: Redesign instrumentation node classes to reduce the public API exposure. - ProbeNode is no longer public - Public interface InstrumentationNode.TruffleEvents is now abstract class EventHandlerNode with package private constructor - Interface ProbeNode.WrapperNode is no longer inside ProbeNode and has been expanded slightly so ProbeNode can be package private
