EDK: Make mojo::platform::TaskRunner's PostTask() take an std::function<void()>.

* Keep the version that takes a base::Closure around for now.
* Propagate this to TestIOThread's PostTask()/PostTaskAndWait().
* Convert many things (esp. in tests) to use lambdas instead of
  base::Bind.

The following problems remain (preventing the eradication of base::Bind,
base::Callback, etc.):
* You can't (in C++11) move-capture, so instances requiring capture of
  move-only types (mostly) remain using base::Bind.
* We're still directly using base::MessageLoop in various places.
