This commit bumps the third-party SQLite to the 3.14.0 pre-release (18:59).
With 3.14.0 the LIKE and EQUALS constraint operators may be mixed within a
query. Previously these would fail to produce a valid set.
As part of the support, each virtual table should choose to bypass rowid-based
deduplication using the new "WITHOUT ROWID" create table epilog. This will
be appended to the schema if the table defines a PRIMARY KEY using index=True.
