cacheable-object: define properties on symbol, allow symbol props

This commit really does two separate things:

* Move the definition for `propertyDescriptors` from that string
  key into `Symbol.for('CacheableObject.propertyDescriptors')`
* Allow and support descriptors for key-based properties, by
  iterating over Reflect.ownKeys() instead of Object.entries()
