[FEA] Properly interface with `dask` `object` -> `arrow[string]` conversions

Is your feature request related to a problem? Please describe.
dask has a behavioral change when pandas-2.x & pyarrow are installed. Some APIs try switching object type columns to arrow[string] for efficiencies arrow strings provide over object types in pandas. This causes a lot of pytest failures in dask_cudf, that is currently being prevented by configured a dask.config: dataframe.convert-string to False. However, this only happens properly for dask.DataFrame's and not for dask_cudf.DataFrame's.

Describe the solution you'd like
We need to update cudf & dask upstream to get this support for dask_cudf.DataFrame as well when the device object is converted to host objects.
