Describe the feature you'd like
As of 10.10, the enum for ItemSortBy offers a lot more options for ordering content. The issue is that not all ItemSortBy work with each BaseItemKind (I think). It would be nice to increase the number of ItemSortBy options based on BaseItemKind or whatever limiting factor exists.

An example is sorting Movies based on .similarityScore results in a 500 Error. My guess is this ItemSortBy is only supposed to be used for "Recommended" sections.

Additionally might be good to move from defaulting from .sortName to .default but in testing I don't know what the difference is.

Additional context
In ItemSortBy we have the following options:

    .default
    .airedEpisodeOrder
    .album
    .albumArtist
    .artist
    .dateCreated
    .officialRating
    .datePlayed

    .seriesSortName
    .videoBitRate
    .airTime
    .studio
    .isFavoriteOrLiked
    .dateLastContentAdded
    .seriesDatePlayed
    .parentIndexNumber
    .indexNumber
    .similarityScore
    .searchScore

Of these, only the following are enabled Swiftfin:

    .premiereDate
    .name
    .sortName
    .dateLastContentAdded
    .random
