doc: sctp: Merge and clean up rst files

The SCTP sections were ending up at the top-level table of contents
under the security section when they should have be sections with the
SCTP chapters. In addition to correcting the section and subsection
headings, this merges the SCTP documents into a single file to organize
the chapters more clearly, internally linkifies them, and adds the
missing SPDX header.
