[Tracking Issue] Refactor lints in misc_early module

[TaKO8Ki]

This issue is linked with #6680.

I've refactored some lints in misc_early module in #7166.

This issue is a tracking issue for splitting the lints one by one, and move them into where they fit most instead of creating a new directory named misc_early.
