Fix sending backtraces across ractors
[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.
