docs: Add contributing document

This completes the migration from the CONTRIBUTING document to the new
in-tree contributing guide. The CONTRIBUTING document itself is
temporarily removed so that git will correctly mark the document as
having been moved. A future change will re-add this document as well as
rework the new contributing document.
