Implement interface to rocprofiler sdk (#695)

* Setting ROCPROF=rocprofiler-sdk environment variable will use rocprofiler-sdk C++ library instead of rocprofv3 python script

* Add runtime option --rocprofiler-sdk-library-path to use custom version of rocprofiler sdk library
    * Add --rocprofiler-sdk-library-path conftest option for tests

* Setup appropriate environment variables to inject rocprofiler sdk code to user command
    * Add env. vars. for counter collection and filtering
    * Add env. vars. for pc sampling

* Use python bindings to list counters supported by rocprofiler sdk
