### Is this a duplicate?

- [x] I confirmed there appear to be no [duplicate issues](https://github.com/NVIDIA/cccl/issues) for this request and that I agree to the [Code of Conduct](CODE_OF_CONDUCT.md)

### Area

CUDA Experimental (cudax)

### Is your feature request related to a problem? Please describe.

These are unmaintained features in CUDASTF (related to scheduling facilities) so they should be removed along with the scheduling facilities.

### Describe the solution you'd like

Entirely remove these values, and the corresponding scheduling facilities, redo from scratch later if needed as the code has changed too much since the experiment

### Describe alternatives you've considered

_No response_

### Additional context
