Test Python 3.13

[dolfinus]

Change Summary

Python 3.13 does not allow inheritance like A -> B, A -> C, B+C -> D, this leads to raising error TypeError: multiple bases have instance lay-out conflict. This was used in 2 cases - mixin classes based on Pydantic models, and inheritance schema like Options(ReadOptions, WriteOptions), ReadWriteFormat(ReadOnlyFormat, WriteOnlyFormat). Replaced with copy-paste of original classes content.

Core tests are failing because PyArrow (dependency of PySpark) does not currently provide https://github.com/apache/arrow/issues/43343 wheels for Python 3.13.
