Separate out T.P.Data, T.P.Translations from T.P.Class. (#8348)

This makes T.P.Class more self-contained, and suitable for extraction
into a separate package if desired.

[API changes]

- T.P.Data is now an exported module, providing `readDataFile`,
  `readDefaultDataFile` (both formerly provided by T.P.Class),
  and also `getDataFileNames` (formerly unexported in
  T.P.App.CommandLineOptions).

- T.P.Translations is now an exported module (along with
  T.P.Translations.Types), providing `readTranslations`,
  `getTranslations`, `setTranslations`, `translateTerm`,
  `lookupTerm`, `readTranslations`, `Term(..)`, and `Translations`.

- T.P.Class: `readDataFile`, `readDefaultDataFile`, `setTranslations`,
  and `translateTerm` are no longer exported.
  `checkUserDataDir` is now exported.

- Text.Pandoc now exports Text.Pandoc.Data and `setTranslations`
  and `translateTerm`.
