FtsQuery class base

A base helper class for composing FTS queries.

This wrapper class and its descendants do not prevent the composition of invalid FTS queries; the goal is only to simplify the composition process by avoiding direct string concatenation and interpolation. For example, the following fragment composes an FTS query using FtsI and FtsP.quote, encloses it in a table-valued function call using SqlT and SqlS, and finally passes the "\"timetable\"('(\"months\": \"january\")')" string to the SQLite.prepare function:

FtsQ ftsQuery = FtsI(["months"], FtsP.quote("january"));
QueryId qid = sqlite.prepare(
  search: SqlT("timetable", SqlS(ftsQuery)),
  /* ... */
