[rocprofiler-compute] Enable running tests from installation only for TheRock setup (#2067)

* Enable running tests from installation only

* Use cmake option -DTEST_FROM_INSTALL=ON to enable running tests from installation folder only
    * It is not possible to run tests from build folder in this case
    * This option prevents changing working directory to source folder

* Fix SourceFileLoader to import rocprof-compute main module correctly

* Install sample executables in the test folder

* fix num_xcds_cli_output test

* Fix tests

* Skip autogen. config. test and add a TODO task for re-design of this
  test

* Add flexible import of source code in test_gpu_specs.py

* Update cmake to install tests/workloads folder when INSTALL_TESTS=ON

* Fix sys.argv[0] for tests

* fix live attach detach test
