[PATCH v2 3/3] docs: submitting-patches: Describe the use of Helped-by tag

[Dragan Simic]

Add the description of the intended use of Helped-by tags, which give credit
to the persons who assisted the patch authors in a way that didn't actually
contribute to the patch directly, i.e. at the source-code level.

 Note, the From: tag is optional when the From: author is also the person (and
