Bump CUDA 12.2.0 to 12.2.1, fix setup support for Cuda 12.1 (#703), Sort compute capabilities sets to select max

* Add support for CUDA 12.1

* Update README to include CUDA 12.1 version

* Add support for >= 12x
Co-authored-by: Jeongseok Kang <jskang@lablup.com>

* Temporary version of bitsandbytes PR 527: Sort compute capabilities sets to select max

* Modify PR 506 to support C++20

* Add Cuda 12.2
