Reviewed by David Kilzer.

A decent chunk of remaining handwritten coders are in ArgumentCodersCF.

The strategy is to add a C++ class to wrap each of the CFTypes we serialize,
and that C++ class's coders are also generated.

CoreIPCData is a prime candidate of this, in that it can easily wrap a CFDataRef.

This patch teachers the generator to look for types that end in "Ref" and are
followed by a "wrapped by" clause.
It then generates the encode/decode methods for that CF type in terms of the wrapper.

CFDataRef and CFStringRef, and already have suitable wrappers, so we'll start with them.
This can also be extended to NS* types in the future.
