CI: Fix creating / staging release

[sieniven]

Summary

• This PR contains the more correct fixes in reference to PR CI: Fix Dirty tag to build release workflow #2706
• Create / staging release workflow waits for multi-arch build jobs and thus the master branch head may have changed during the workflow
• Or when setting the release, master branch may not be on the commit that the release tag is set on
• The PR removes explicit checking out of master branch ref in build-release / build-staging pipelines respectively so that we will ensure the correct git commit version in this step
• Instead when generating build.h file, we will skip git dirty check when the current git commit equals to the reference tag
