…9458) This PR implements `DataFrame.hash_values`, which will replace `DataFrame.hash_columns` (which is deprecated in this PR). This proposal was discussed offline with @vyasr and in the weekly cuDF Python dev meeting. This unifies the method name and signature for `Series.hash_values` and `DataFrame.hash_values`, enabling future internal refactoring by moving the method's implementation to the `Frame` class (though I'm waiting for the removal of `Series.hash_encode` to follow up on this so it can be done in a single pass, see #9381 and #9457).

This PR removes the deprecated method `Series.hash_encode`. Resolves #9475. Follows up on #9457, #9381. This PR also removes libcudf code paths used solely for this Python method. Users may replace code like `series.hash_encode(stop, use_name=False)` with `series.hash_values(method="murmur3") % stop`.
