We should have some API in xarray.Index to update the index when its corresponding coordinate variables are renamed.

This currently implemented here where the underlying pd.Index name(s) are updated: https://github.com/pydata/xarray/blob/c5530d52d1bcbd071f4a22d471b728a4845ea36f/xarray/core/dataset.py#L3299-L3314

This logic should be moved into PandasIndex and PandasMultiIndex.

Other, custom indexes might also have internal attributes to update, so we might need formal API for that.
