Move validation test suite to GitHub Workflows

- Perform a shallow clone of submodules analyzed in validation
  test suite in GitHub workflows (should take around 30 seconds)
- Switch badge in README.md to GitHub Workflows and update default
  branch for badge.
- Remove travis config
- After microsoft#385 is merged run_phpstan.sh can remove the separate install
  step (as a followup PR)
