kunit: tool: make --json do nothing if --raw_ouput is set
When --raw_output is set (to any value), we don't actually parse the test results. So asking to print the test results as json doesn't make sense. We internally create a fake test with one passing subtest, so --json would actually print out something misleading. This patch: * Rewords the flag descriptions so hopefully this is more obvious. * Also updates --raw_output's description to note the default behavior is to print out only "KUnit" results (actually any KTAP results) * also renames and refactors some related logic for clarity (e.g. test_result => test, it's a kunit_parser.Test object). Notably, this patch does not make it an error to specify --json and --raw_output together. This is an edge case, but I know of at least one wrapper around kunit.py that always sets --json. You'd never be able to use --raw_output with that wrapper.
