Description
### Describe the enhancement requested
Split off from #34153.
In order to take advantage of sorted columns, it would be necessary for arrow to standardize on a way to represent sorting in datasets/table metadata. Akin to to pandas' `index_columns`.
### Component(s)
C++, Python
Contributor guide
Research direction
The issue names no files, tests, or entry points. Start by reviewing the split-off context in #34153 and the pandas `index_columns` analogy, then determine how a sorting representation should be standardized across C++ and Python dataset/table metadata. Done means an agreed metadata standard is defined and its scope is clear.
