Documentation: kernel-doc: Promote two chapter headings to page title

Promote "Writing kernel-doc comments" heading to page title, in
accordance to kernel documentation guidelines. Also promote "Including
kernel-doc comments" heading because both headings deserve their own
chapters in PDF output.

There is no differences in the resulting output except formatting
semantics.
