[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) ANN_BENCH #130 (comment)
• name of index class (in ann_type.hpp) ANN_BENCH #130 (comment)
