ci: run static-build workflows on 'static-build-ci' label

Sometimes, we only need to test static-build, e.g. when we apply a patch
to a third party sub-project. Let's introduce a new label to run the ci
checks faster in this case.

NO_DOC=ci
NO_TEST=ci
NO_CHANGELOG=ci

(cherry picked from commit 09a77cd7)
