Initialize the caller-allocated invoker structure with a cache of information needed to invoke the C function corresponding to info with the platform's default ABI.

A primary intent of this function is that a dynamic structure allocated by a language binding could contain a GIFunctionInvoker structure inside the binding's function mapping.

Prepares a callback for ffi invocation.
