Make mojo::internal::MultiplexRouter::InterfaceEndPoint RefCountedThreadSafe

Make mojo::internal::MultiplexRouter::InterfaceEndPoint RefCountedThreadSafe

InterfaceEndPoint's ref count is a non-thread-safe, and is used behind a
lock. The usage of it is not racy, but an upcoming change to add an
assertion to RefCounted requires a suppression here.
This CL converts InterfaceEndPoint to RefCountedThreadSafe, which doesn't
need the suppression, regarding the atomic operations is lightweight
comparing to a lock that covers the object itself, and RefCountedThreadSafe
less error prone for cross thread usage.
