feat(devtool): compress test_results for CI uploads

Now `test_results` will contain a lot of files and directories
with all test metrics and data files.
To speed up upload and download of test_results, compress it's
content if tests are run in CI.
Also add an `--no-archive` option to skip archiving if needed.
