Michael Starzinger e16775163a [wasm] Preserve identity on {WasmJSFunction} re-export. 
This preserves the object identity of a {WebAssembly.Function} instance
that is being re-exported by a module. Such functions are considered to
have an internal [[FunctionAddress]] slot and hence require their object
identity to be preserved (similar to {WasmExportedFunction} already).
