sql: test purge of search tokens (#86527)

introduce a new mechanism to implement FTS with fuzzy-match.
This is made possible by adding and maintaining a table of the
FTS tokens, wcs_search_tokens, fed with searchable_formdefs
and wcs_all_forms.
When a query is issued, its tokens are matched against the
tokens with a fuzzy match when no direct match is found, and
the query is then rebuilt.
