src: create handle scope in FastInternalModuleStat

It needs a handle scope for the context handle. Since the
FastApiCallbackOptions struct doesn't have isolate on it
in V8 12.4 on Node.js 22, use Isolate::TryGetCurrent() to
get to the isolate needed for the handle scope creation and
fallback to the slow callback if no isolate is entered.
