[FEA]: Deprecate `cuda::bit_reverse`

We have `cuda::std::bit_reverse` now, we should deprecate the `cuda::` version and move the implementation to `cuda::std::` namespace

Locate the existing cuda::bit_reverse implementation and the cuda::std::bit_reverse implementation, then read the surrounding tests and namespace conventions. Deprecate the cuda:: version while moving the implementation to cuda::std::, and update or add coverage showing both the new location and deprecation behavior.
