DDC-3437: [GH-1213] fix instantiation of embedded object in ReflectionEmbeddedProperty

Url: #1213

Message:

Recently, ReflectionEmbeddedProperty was updated to extend ReflectionProperty. This broke any embeddable that extends an abstract class. That's because if a property is defined in the abstract class, $this->class is alway the abstract class and thus cannot be instantiated. The $class parameter that is passed into the constructor needs to be stored, and that class should be instantiated, not the the property's declaring class.
