stuartmorgan 9db5c3fb62 Fix C++ MethodChannel reply type (flutter/engine#17607) ...

Makes InvokeMethod's reply a high-level response object, rather than
binary data, matching the abstraction level of the class (and the other
languages' implementations).

In support of that:
- Adds the logic to the codecs to decode response envelopes, which had
  never been implemented.
- Adds a convience implementation of MethodResult that forwards to
  lambdas, so that one-off invocation handlers are easier to write.

Also simplified BinaryMessenger's API so that subclasses only need to
implement one version of Send, rather than two almost-identical versions.
