Alex Gaynor 0f01791ffc Bug 1512990 - Part 4 - remove declarations of Recv/Answer methods from IPDL protocol base class; r=froydnj
For cases where the class has direct calls (that is, we cast `this` to the
subclass before making the call) no longer declare Recv/Answer methods on the
base class at all. This should ensure that slots for them are not generated in
vtables, and also allow the derived class to choose the method signature (e.g.
whether it wants to take something by reference or by value).
