> Implement a new TypeInfoDataTypeConverter that will no longer produce LegacyTypeInformationType.
> As mentioned in the FLIP:
> - All types from DataStream API should be supported by this converter.
> - TupleTypeInfoBase will be translated into a proper RowType or StructuredType.
> - BigDecimals will be converted to DECIMAL(38,18) by default.
> - Composite types (tuples, POJOs, rows) will be flattened by default if they are used as top-level records (similar to the old behavior).
> - The order of POJO field's is determined by the DataTypeExtractor and must not be defined manually anymore.
> - GenericTypeInfo is converted to RawType immediately by considering the current configuration.
> - A DataStream that originated from Table API will keep its DataType information due to ExternalTypeInfo implementing DataTypeQueryable.
