Override UInt64 enum test to handle MariaDB serialization difference

Added override for Can_read_write_ulong_enum_JSON_values that detects the database type at runtime and adjusts the expected JSON format:
- MySQL: Uses -1 for UInt64.MaxValue
- MariaDB: Uses 18446744073709551615 for UInt64.MaxValue

The override normalizes the expected JSON based on AppConfig.ServerVersion.Type to ensure tests pass on both database platforms.

Note: The base class JsonTypesRelationalTestBase has test cases with InlineData attributes that cannot be fully intercepted. This approach handles most cases but may need additional refinement for edge cases where the base class test discovery interferes with the override.
