Mojo C++ bindings: add perf tests to compare performance of Router/MultiplexRouter.

These two test cases do same-thread ping-pong using Router and MultiplexRouter:

MultiplexRouter is about 95% as fast as Router:

[ RUN      ] MojoBindingsPerftest.RouterPingPong
RouterPingPong/ 144546  pings/second
[       OK ] MojoBindingsPerftest.RouterPingPong (702 ms)
[ RUN      ] MojoBindingsPerftest.MultiplexRouterPingPong
MultiplexRouterPingPong/  137701  pings/second
