Support performance tests while direct tests commands keep unchanged. To build performance tests, run "make build_perf". To run all performance testis, run "make perf". To run specific tests, for example, run /usr/bin/ctest -C performance -R performance_tests/perfDispatch --verbose To run individual test, for example, run performance_tests/memory/hipPerfMemMallocCpyFree Change-Id: I168c1b9ef1ec21b392d48648d0c71e8fbd37d57b
