build: inline external Github Actions to unblock CI

[ktmud]

SUMMARY

Apache changed policy on Github Actions because of security risks. Now official apache repos can only run a list of allowed actions.

CI has been blocked by this error:

styfle/cancel-workflow-action@0.6.0 and apache-superset/cached-dependencies@b90713b are not allowed to be used in apache/incubator-superset. Actions in this workflow must be: created by GitHub, verified in the GitHub Marketplace, within a repository owned by apache or match the following: apache/, dawidd6/action-download-artifact@, gradle/wrapper-validation-action, gradle/wrapper-validation-action@, peter-evans/create-pull-request@, scacap/action-surefire-report@, shivammathur/setup-php@.

This PR unblocks CI by

1. Remove styfle/cancel-workflow-action, which may soon become obsolete if build: try to speed up Github workflows #11944 gets merged

2. Move all other external dependencies to be within current repo, including:

   • apache-superset/cached-dependencies or ktmud/cached-dependencies
   • MorrisonCole/pr-lint-action
   • unsplash/comment-on-pr
   • trilom/file-changes-action

   These actions were copied over via downloading them as ZIP files directly from GitHub. All of these actions use the MIT license so I'd assume there is no licensing issue.

3. Change pull_request_target trigger for the E2E action to pull_request. This is needed for unblocking the CI that runs on existing workflow configs. This will also prevent future Pwn requests and we don't plan to bring it back.

Thanks for taking this on. Minor typo, other than that makes sense and LGTM.
