Implement timezone normalization and consistent handling for DateTime types

[traceon]

• Consider adding a parameter, that controls, whether the dates/times should be converted to some target timezone at all or the server/column timezone should be used, when presenting data in ODBC timestamp etc. data structures, that are timezone-unaware.
• Implement timezone conversion for all formats. All the machinery is ready, only the conversion should be implemented. Currently, RowBinaryWithNamesAndTypes is not consistent with ODBCDriver2. See:
  • https://github.com/ClickHouse/clickhouse-odbc/blame/master/README.md#L112
  • DateTime tests (all tests should not depend on server or local timezones and wire formats)
  • WireTypeDate***AsInt structs and their conversion methods.
