  -----------
  Stop using Vector::unsafeAppendWithoutCapacityCheck() in JSObject::putOwnDataPropertyBatching()
https://bugs.webkit.org/show_bug.cgi?id=265084

Reviewed by Darin Adler.

Update the `Vector<T>(size_t, Functor)` to abort appending if the Functor
returns a std::optional<T> type that is std::nullopt.

Adopt it in JSObject::putOwnDataPropertyBatching() to avoid calling
Vector::unsafeAppendWithoutCapacityCheck() explicitly.
