Convert a subset of the ctest to pytest to be used in TheRock CI.
Create a new cmake flag `ROCPROFSYS_INSTALL_TESTING` to control test suite installation.
- pytest package will be installed to share/rocprofiler-systems/tests
- all compiled examples are put in share/rocprofiler-systems/examples
- all test relevant scripts are put in share/rocprofiler-systems/tests
- see README.md in share/rocprofiler-systems/tests
