Use `rapids_cpm_nvcomp` in `get_nvcomp.cmake`

[vyasr]

Our get_nvcomp.cmake should be updated to use rapids_cpm_nvcomp from rapids-cmake. That will keep kvikio from getting out of sync with the rest of RAPIDS and better ensure that it stays up to date. I believe that there have been a lot of relevant bugfixes/improvements (for cudf) to nvcomp in the last couple of releases.

I used the .cmake file you recommended @vyasr and will update this with a PR later.
