orc_rt_WrapperFunctionResult is a byte-buffer with inline storage and a builtin error state. It is intended as a general purpose return type for functions that return a serialized result (e.g. for communication across ABIs or via IPC/RPC). orc_rt_WrapperFunctionResult contains a small amount of inline storage, allowing it to avoid heap-allocation for small return types (e.g. bools, chars, pointers).
