[Bug #21818] Currently exceptions can be sent across ractors, but because of a limitation in the TypedData API, the exception backtrace is duped as an empty backtrace. The problem is that backtraces are embedded objects, hence the classic `rb_class_alloc(klass)` API is insufficient because we need to know the size of the Backtrace object we're duping to instantiate the copy. This is worked around by changing Ractors to call `#clone` on objects rather than use `rb_obj_clone`, and to implement `Thread::Backtrace#clone` to properly clone the variable size object.
