ext/pdo_sqlite: document the PHP 8.5 additions and behaviour changes

[lacatoire]

Documents the PHP 8.5 changes of ext/pdo_sqlite: the new Pdo\Sqlite::setAuthorizer() method and its OK/DENY/IGNORE constants, the new ATTR_BUSY_STATEMENT, ATTR_EXPLAIN_STATEMENT, EXPLAIN_MODE_* and ATTR_TRANSACTION_MODE/TRANSACTION_MODE_* constants, the raised libsqlite requirement, the null byte handling of PDO::quote() and the return type check of the collation callback.

The collation entry is scoped to the deprecated PDO::sqliteCreateCollation() alias: Pdo\Sqlite::createCollation() already threw before 8.5 (php-src ext/pdo_sqlite/pdo_sqlite.c, php_sqlite_collation_callback()).
