feat(bigquery-jdbc): implement parameter setters in PreparedStatement

[Neenu1995]

b/535194644

• Parameter Setter Overloads (BigQueryPreparedStatement.java):
  • Implemented missing JDBC parameter setters: setShort, setByte, setInt, setLong, setFloat, setDouble, setBigDecimal, setBoolean, setString, setBytes, setObject, and setNull.
  • Delegates parameter binding to BigQueryParameterHandler with correct Java type metadata.
• Transport-Layer Value Widening (BigQueryParameterHandler.java):
  • Added value widening in configureParameters(...) when constructing QueryParameterValue:
    • Widens Short, Byte, and BigInteger $\rightarrow$ Long for StandardSQLTypeName.INT64.
    • Widens Float $\rightarrow$ Double for StandardSQLTypeName.FLOAT64.
  • Resolves runtime IllegalArgumentException: Type INT64 incompatible with java.lang.Short during query execution.
• JDBC Metadata Preservation (BigQueryJdbcTypeMappings.java):
  • Retained standard mappings (Types.SMALLINT $\rightarrow$ java.lang.Short, Types.TINYINT $\rightarrow$ java.lang.Byte).
  • Ensures ParameterMetaData.getParameterClassName() remains 100% compliant with JDBC standards.

Code Review

This pull request implements several previously unsupported JDBC setter methods in BigQueryPreparedStatement, including setNull, setShort, setBytes, setObject, and setArray, along with corresponding type mappings in BigQueryJdbcTypeMappings and comprehensive unit and integration tests. The review feedback highlights opportunities to improve type consistency by mapping Types.SMALLINT and Types.TINYINT to Short.class and Byte.class respectively, propagating SQLException in setNull instead of silently swallowing it, and simplifying setShort to use Short.class directly.
