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).

When calling a Recv/Alloc/Dealloc method on most types, cast `this` to the
derived class.
There is a heuristic to figure out what the correct derived type is. There is a
blacklist of types which we can't do direct calls on for the moment, as well as
an override for types that do work with direct calls but which don't match the
heuristic.

We will use the new type for the generated IPDL message handler
prototype to make sure correct error handling method is called.

The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
CLOSED TREE makes big refactorings like this a piece of cake.
