Issue: https://github.com/single-cell-data/TileDB-SOMA/issues/2765

Changes: ExperimentAxisQuery.to_anndata iterates through each column and drops unused categories.

Notes for Reviewer: This change was originally proposed in https://github.com/single-cell-data/TileDB-SOMA/pull/2811 but was suggested somacore was a more appropriate location for it.

As placeholder I have chosen drop_levels but will change to the agreed upon name.
