[JSC][Wasm] Support WebAssembly.Exception options.traceStack
https://bugs.webkit.org/show_bug.cgi?id=319826
Reviewed by Keith Miller.
Accept the optional ExceptionOptions argument on WebAssembly.Exception.
When traceStack is true, capture a stack and store it under a private
name; expose it via a prototype getter (IDL attribute). Default remains
no stack. Set the constructor length to 2 to match the IDL.
Keep Error on CommonIdentifiers::stack. Register stackPrivateName as a
private-only special case (like polyProto) so Exception storage does not
introduce a second public "stack" Identifier.
