[FEA] ANN bench improvements

[tfeher]

During porting the ANN benchmarks from RAFT (#130), a list of potential improvements was created:

• [ ] clang-tidy: cleanup naming conventions
• [ ] cleanup/unify logging (including CPU-only builds)
• [ ] fix/unify create_algo + create_search_param syntax
• [ ] actualize cuda_stub.hpp for cpu-only builds
• [ ] make sure there's no direct cuda dependencies in benchmark.hpp
• [ ] add the memory interconnect info to benchmark context
• [ ] add command line string which used for running the benchmarking to the benchmark context
• [ ] add more information about CPU cores and RAM to the benchmark context
• [ ] etc...

Suggestions for improved naming

• [ ] benchmark name (in build.sh) https://github.com/rapidsai/cuvs/pull/130#discussion_r1619512483
• [ ] name of index class (in ann_type.hpp) https://github.com/rapidsai/cuvs/pull/130#discussion_r1619515306
