Avoid automatic creating of Index variable when nD variable shares name with one of its dimensions.

Closes #2233

```python
url = ""http://www.smast.umassd.edu:8080/thredds/dodsC/FVCOM/NECOFS/Forecasts/NECOFS_GOM3_FORECAST.nc""
ds = xr.open_dataset(url, engine=""netcdf4"")
display(ds)

xr.testing._assert_internal_invariants(ds, check_default_indexes=False)  ! no raise on #7368
```

~The internal invariants assert fails on `main` but succeeds on #7368~. EDIT: now fixed the invariants check.

A minimally invasive solution to #3351. If `variable.encoding[""coordinates""]` is specified, we write that attribute to disk and warn the user that roundtripping may not work.

*Use case:* Just like `dayofyear` but easier to interpret when only looking at 1 year of data. 

*Example:* Start with `da.time`
```
<xarray.DataArray 'time' (time: 8737)>
  array(['2014-01-01T00:00:00.000000000', '2014-01-01T01:00:00.000000000',

  Coordinates:
    * time     (time) datetime64[ns] 2014-01-01 2014-01-01T01:00:00 ...
