[FIXED JENKINS-46252] Mark Declarative jobs with DeclarativeJobAction

If we are in a Declarative run, mark the parent job as a Declarative
job via DeclarativeJobAction, if it's not already present. Note that
we never remove this - if a job was ever once Declarative, we still
count it as such. Imperfect, but close enough.
