feat(bigquery-jdbc): standardize parameter handling and calendar defensive copying across statement interfaces (#13805)

b/535194644

* **Hardened CallableStatement Getters**: Replaced reversed
`isAssignableFrom` checks with `instanceof`, `Number`/`Date` coercions,
and direct delegation to `getObject()`.
* **Standardized JDBC Parameter Names**: Updated synthetic parameter
names (`arg0`, `arg1`) to standard JDBC names (`parameterIndex`,
`parameterName`, `scale`).
* **Symmetrical Timezone Coercion**: Centralized `Calendar` timezone
conversions using `java.time` APIs across statements and result sets.
* **ParameterMetaData & Dynamic Modes**: Added support for dynamic `IN`,
`OUT`, and `INOUT` parameter modes in `BigQueryParameterMetaData`.
* **PreparedStatement Hardening**: Added defensive copying for
`Calendar` setters and replaced silent stubs with explicit unsupported
feature exceptions.
