Add test infrastructure to run castxml and validate results

Create a test/run.cmake test driver script that uses execute_process to
run a castxml test command line and then compares the results to those
we expect.  Validate the process result (return code) and the content of
stdout and stderr.  In test/CMakeLists.txt create a castxml_test_cmd
macro to add tests that use "run.cmake".
