Support custom message filtering on Mojo binding objects
* Replaces MessageFilter with MessageReceiver
* Updates FilterChain to always end on the sink, short-circuiting
if any "filter" (receiver) rejects along the way
* Adds a new AddFilter() interface to mojo::Binding and
mojo::AssociatedBinding, allowing users to inject MessageReceiver
filters to be run immediately before every message dispatch
