Add support for BM25/Lexical sort on "analyzed text" indexed Table columns

[tatu-at-datastax]

In addition to BM25/Lexical filtering (#2053) for Tables, we also need to enable BM25/Lexical sorting, similar to how Collections supported it (and somewhat similar to Vector/ANN sorting).

NOTE: this may depend on #1838 as pre-req.
