Change the cpp wrappers of audio input/video capture to use CompletionCallbackWithOutput.

And also fix a few bugs in the PP_ArrayOutput and CallbackWithOutput code.
- Make sure POD members of Dispatcher\.* are properly initialized.
- Avoid leaking var/resource references in DispatcherWithOutput\.*::operator().

BUG=None
TEST=None
