Expand description

Implement InfoFfi for a type by converting through another type.

The argument $MidTy argument must implement From<$SrcTy> and InfoFfi.

This is provided (even though it’s trivial) because it is always safe (well, so long as $MidTy’s IntoFfi implementation is correct), but would otherwise require use of unsafe to implement.
