Docs/mm/damon/design: add a section for kdamond and DAMON context
The design document is not explaining about the concept of kdamond and the DAMON context, while usage document does. Those concept explanation should be in the design document, and usage document should link those. Add a section for those.

+Execution Model and Data Structures
+===================================
+
+The monitoring-related information including the monitoring request
+specification and DAMON-based operation schemes are stored in a data structure
+called DAMON ``context``. DAMON executes each context with a kernel thread
+called ``kdamond``. Multiple kdamonds could run in parallel, for different
+types of monitoring.
