Update type checkers and reduce exclusions

[Avasam]

• Bumped pyright and mypy
• Set pyright's typeCheckingMode to "standard"
• Enable allow_redefinition and allow_redefinition_new in mypy for more flexible redefinitions and less idiosynchrasies
  • but requires also enabling local_partial_types which means more assignements needed to be explicitly typed
• Fix one-offs mypy errors that would appear if enabling check_untyped_defs
  • and typed those functions so mypy now checks them
• Add new error codes to temporarily ignore from mypy and pyright
• Cleanups in affected areas
  • Especially usages of RunScript
