[PATCH] checkpatch: add check for tag Co-Developed-by

Recently signature tag Co-Developed-by was added to the
kernel (Documentation/process/5.Posting.rst). checkpatch.pl doesn't know
about it yet. All prior tags used all lowercase characters except for first
character. Checks for this format had to be re-worked to allow for the
new tag.

Add checkpatch checks for Co-Developed-by tag.
