[FEA] Use nvbench instead of google benchmark in cuML C++ benchmarks

[teju85]

Is your feature request related to a problem? Please describe.
nvbench is a more "GPU oriented" benchmarking tool than google benchmark. We currently use google benchmark for all of our C++-side benchmarking.

Describe the solution you'd like
Migrate to using nvbench instead of google benchmark, in the long run.

Describe alternatives you've considered
We could stay with google benchmark, but will have to also maintain our customizations (almost all of which are already addressed in nvbench!).
