Docs/mm/damon/design: add links from overall architecture to sections of details

DAMON design document briefly explains the overall layers architecture
first, and then provides detailed explanations of each layer with
dedicated sections.  Letting readers go directly to the detailed sections
for specific layers could help easy browsing of the not-very-short
document.  Add links from the overall summary to the sections of details.
