fix(python): Only call unnest for objects implementing __arrow_c_array__ if a pyarrow.RecordBatch

[mroeschke]

closes #23068

Redo of #23069 based of the feedback of #23194, only calls unnest if the object is a pyarrow.RecordBatch

For context in cudf_polars, we'd like the ability to perform pl.from_arrow(cudf_object) that implements __arrow_c_array__
