gha: ensure that self hosted runner is prepared before running the workflow

This PR ensures that the self hosted runner is prepared by taking
necesary actions before running the workflow. The script prepare_runner.sh
checks the following:
1. Ensure that containerd/docker is up and running
2. Make sure that the repository workspace is cleaned up and has no conflicts
3. Remove/cleanup any leftover files from the previous runs

Fixes: #9262
