chore: Remove deprecated APIs

BREAKING CHANGE: the following deprecated APIs have been removed:
- `queryTypes` bag of parsers -> use individual `parseAsXYZ` parsers
  for better tree-shakeability.
- `subscribeToQueryUpdates` helper -> since Next.js 14.0.5,
  `useSearchParams` is reactive to shallow search params updates
  in the app router. See #425.
- Internal types and aliases
