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

As a user of CCCL's device-side algorithms, I would like the ability to do something like a cooperative, device-wide scan or reduction using _all_ threads in the grid.

This EPIC is to capture requests related to device-scope cooperative algorithms.

### Describe the solution you'd like

Provide, cooperative, device-wide algorithms like scan, reduce, etc.

### Describe alternatives you've considered
