Expose upstream DataFusion v53 utility methods: session_start_time, enable_ident_normalization, parse_sql_expr, execute_logical_plan, refresh_catalogs, remove_optimizer_rule, and table_provider. The add_optimizer_rule and add_analyzer_rule methods are omitted as the OptimizerRule and AnalyzerRule traits are not yet exposed to Python. Closes apache#1459.
