Fix getParameterMetaData crash with table-valued parameters

[divang]

Fix getParameterMetaData() crash with table-valued parameters (#2744)

Problem:
• PreparedStatement.getParameterMetaData() was crashing with SQLServerException when table-valued parameters (TVP) were used
• Error: "A metadata error for the parameter {0} occurred" when calling getParameterMetaData() on statements with TVP

Root Cause:
• The parseQueryMeta() method in SQLServerParameterMetaData assumed all user-defined types (when suggested_system_type_name is null) were assembly types
• For table-valued parameters, suggested_system_type_name is null but suggested_user_type_name contains the table type name
• The code incorrectly queried sys.assembly_types for TVP types, which are actually table types with system_type_id = 243

Solution:
• Added STRUCTURED_TYPE constant (243) to identify SQL Server structured/table types
• Enhanced parseQueryMeta() to check suggested_system_type_id before determining type handling
• For TVP (system_type_id = 243):

• Set parameterType to microsoft.sql.Types.STRUCTURED
• Set parameterClassName to Object.class.getName()
• Extract metadata directly from sp_describe_undeclared_parameters result
• Skip SSType processing since TVP metadata is handled directly
  • Maintained backward compatibility with existing assembly type handling

Testing:
• Added comprehensive test cases in ParameterMetaDataTest for TVP scenarios
• Validates getParameterMetaData() works correctly with table-valued parameters
• Ensures parameterCount, parameterTypeName, parameterType, and parameterClassName return correct values
• Covers the specific scenario reported in issue #2744
• Maintains compatibility with existing parameter metadata functionality

Fixes #2744
