Resolve various type errors with New Type Solver

[whoamimaybeme]

This PR should resolve as many type errors within the New Type Checker as possible without forcing the New Type Checker onto the EToH v6 kit. Since the old type checker is leaving soon, it's probably best to get as many of these issues out of the way before it gets forced.

There will be future pull requests that will come after this one is merged that will resolve the rest of the type errors and will potentially cause a few minor changes to how the v6 kit functions.

A few notes

• None of the current changes proposed are final. This is a draft!
• I wish to try and reduce how much of the code is changed.
  • Example: I wish to use type casts for Players.LocalPlayer instead of using a bunch of if then statements.
• I try to use "" and math.nan as replacements for the Utility.Config.Type types. Instances of this include within the MusicZoneEditor and the JumpLauncher.
