Improve templates for C++ Restbed (#10543)

* Improve templates for C++ Restbed

The templates now generate classes which have virtual functions that can
be overridden to implement handlers.

* Fix missing HTTP methods in generated restbed C++ code

There was a wrong handling of "x-codegen-other-methods".
