* xds-k8s jobs: standardize TESTING_VERSION (#30027) (#30048)

This Addresses the issue with skips not working in golang tests, ref b/235688697. 

1. Unifies `TESTING_VERSION` detection  in grpc_xds_k8s_install_test_driver.sh - new approach applicable to all languages.
2. Use `TESTING_VERSION` in all build files in `--testing_version` and when tagging docker images. This will be backported to all active test branches. Build Scripts in all other languages will be updated as well.
