LibSQL: Limit the number of nested subqueries
SQLite hasn't documented a limit on https://www.sqlite.org/limits.html for the maximum number of nested subqueries. However, its parser is generated with Yacc and has an internal limit of 100 for general nested statements. Fixes https://crbug.com/oss-fuzz/35022.
