ZM8: Make cutscene in lower delkfutt tower optional

[Xaver-DaRed]

I affirm:

• I understand that if I do not agree to the following points by completing the checkboxes my PR will be ignored.
• I understand I should leave resolving conversations to the LandSandBoat team so that reviewers won't miss what was said.
• I have read and understood the Contributing Guide and the Code of Conduct.
• I have tested my code and the things my code has changed since the last commit in the PR and will test after any later commits.

What does this pull request do?

This goes against logic, narrative coherence and hurts me deeply. But it's true.
Simplified logic while I was there, using the Option variable to track events as a bitmask

Steps to test these changes

1. Start ZM8.
2. Go to Stellar Fulcrum. Watch cutscene.
3. Exit and zone to lower delkfutt tower.

Watch the cutscene play and make absolutely no sense.
