Improve handling of FTS5 hidden columns

[watbe]

FTS5 tables have different hidden columns compared to FTS3 and FTS4: https://www.sqlite.org/fts5.html#sorting_by_auxiliary_function_results

This PR does the following:

1. Change the synthesizedColumns logic to differentiate FTS3 and 4 from FTS5.
2. Add rank, rowid and _rowid_ to the list of synthesizedColumns for FTS5
3. Add some tests

Fixes related problem sqldelight/sqldelight#5981

This does not prevent users from attempting to create invalid FTS5 tables using rank or rowid as column names, but they'll get an error at runtime from sqlite anyway.

Thanks to @griffio for the pointer from the linked issue!
