Code Editor 2: Duplicated child objects do not highlight as inheriting from the parent properly until reload

[KormexGit]

Description

If you duplicate a child object, the duplicate won't highlight any of the parent's variables in any events. Additionally, if you rename the duplicate, feather will start showing a GM2040 error on any event_inherited calls, saying that the object has no parent with that event even though it does.

Steps To Reproduce

1. Create two objects, make one the child of the other.
2. Set up some variables in the create event of the parent.
3. Have the child use those inherited variables, and call event_inherited() in create.

• Note: If following these steps from the start, the not-duplicated child will not highlight the parent variables properly due to Code Editor 2: Changing an object's parent does not register in multiple ways #7937, so you will need to reload the project after assigning the parent.

4. Duplicate the child. The duplicate will not highlight parent variables.

Fixed. The Server did not read .yy files when the DidCreateFile event was dispatched.
This is not a straight forward fix because the Client may or may not have serialized the .yy file to disk by the time it dispatches the event. CoreResources dispatches events between a Duplicate, LoadProject, and CreateNewResource paths at different points in time with relation to disk serialization.

Please test this fix carefully by attempting to create many different resources in as many ways as possible. The fix for this made several assumptions about what ProjectInfo state indicates.
