[Credits] Add multiple roles on cast and crew credits

[Divinelink]

This pull requests enhances the cast and crew credits by adding multiple roles to people that have such information.

Each actor or crew member in a series might take on multiple roles, with each role potentially having a different episodeCount. To address this, we modified our queries to retrieve all roles, cast and crew information separately, then appropriately matched and appended the correct roles to each individual.

To address any performance issues (especially in series with thousands of cast members and roles) we're using the kotlin's groupBy operator, that associates each role to a castId

val rolesByCastId = database.seriesCastRoleQueries
   .fetchRoles(aggregateCreditId = id)
   .executeAsList()
   .groupBy { it.castId }

This ensures that finding all roles for a given person becomes a negligible-cost operation:

  database
    .seriesCastQueries
    .fetchSeriesCast(id)
    .asFlow()
    .mapToList(dispatcher.io)
    .map { listOfCast ->
      listOfCast
        .map { cast ->
          val roles = rolesByCastId[cast.id] ?: emptyList()
          cast.toEntity(roles = roles)
        }
        .filter { it.roles.isNotEmpty() }
    }

Additionally:

• Added the role on the Known For section for each person
• Added Jetpack screenshot tests library
