This makes WebView::Database wrap around sqlite3 instead of LibSQL. The effect on outside callers is pretty minimal. The main consequences are: 1. We must ensure the Cookie table exists before preparing any SQL statements involving that table. 2. We can use an INSERT OR REPLACE statement instead of separate INSERT and UPDATE statements.
