This patch contains two preparatory changes for exposing the C++
PaymentAppService via JNI:
1. Replace the output parameter of PaymentAppService::Create() with a
   separate method that callers can use to get the number of payment
   factories. This will make it easier for the upcoming JNI code to
   first query the number of factories, cache it in a delegate, and
   call Create() with the delegate.
2. Added two new utility helpers to deserialize Mojo objects from
   Java ByteBuffers.
