Subject: [PATCH 3/8] Docs/mm/damon/index: mention DAMOS on the intro

What DAMON aims to do is not only access monitoring but efficient and
effective access-aware system operations. And DAMon-based Operation
Schemes (DAMOS) is the important feature of DAMON for the goal. Make
the intro of DAMON documentation to emphasize the goal and mention
DAMOS.
