Move (most of) SierraQueryOps from Scala-libs to transformer_sierra

[paul-butcher]

Most of SierraQueryOps is only used in transformer_sierra, so it shouldn't be in a separately compiled library.

ItemDataOps.displayNote is used in both the API and the transformer, so a decision will need to be made as to whether to preserve the DRYness or simply copy it into both places. Given that there is already quite a lot of similarity between the two versions of SierraItemAccess, I think a bit of copy-paste is perfectly acceptable.
