Mojo C++ bindings: support sync methods - part 1.

This CL:
- adds support for [Sync] attribute;
- generates C++ sync method signatures;
- does the simplest thing to block and wait for results of sync calls. (Allows
  any messages of the same interface ptr to re-enter; disallows any messages of
  other message pipes to re-enter.)

The following will be in future CLs:
- Change the re-entrancy behavior.
- Support sync calls with associated interfaces.
