pdo_stmt_setup_fetch_mode() cleared active fetch state before validating the replacement. Failed validation lost FETCH_INTO objects and FETCH_CLASS constructor arguments; autoload re-entry could also observe a mismatched tagged union. Validate the candidate entirely in local storage. Only after validation succeeds, replace the active payload and mode, and release the old payload from a coherent state. Closes phpGH-23188

PDOStatement::setFetchMode() discarded active FETCH_INTO or FETCH_CLASS state before validating its replacement. Validate the candidate in local storage, then replace the tagged-union payload and release the old state after a coherent commit. This preserves state on validation failure and makes autoload or destructor re-entry safe.
