[Status effects] Add tiers to spell effects, action choose system and related systems

[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?

• Adds tiers to spell effects.
• Adds new data column for incompatible effects based exclusively on tier.
• Adds logic to status effect data, to check tiers.
• Applies tier checks to action-choose system.
• Edits several Slow/Haste actions.

And with that, the real meat:

• Introduces a new file to handle mobskills that apply status effects on enemies. Only used on "Spider Web" mobskill, as an example.

The reason for this is because our current system doesnt handle tiers. And it also sucks, it's old and I fucking hate it, so screw it.

Steps to test these changes

Battle. Use spells.

Just going to link the open issue about slow/haste tiers so I can close it whenever this gets merged.
