Delete orphaned test-on-gdk CI child pipeline

Harsha Muralidharrequested to merge
hm-remove-gdk-e2e-ci-jobs into master

What

  • Delete the unused .gitlab/ci/test-on-gdk/ child pipeline folder.
  • Remove its dead pattern entries in rules.gitlab-ci.yml and its CODEOWNERS line.

Why

MR !255349 (merged) removed the jobs that triggered this folder. Nothing includes or triggers it anymore, so it is dead weight.
