samples/damon: implement a DAMON module for memory tiering
Implement a sample DAMON module that shows how self-tuned DAMON-based
memory tiering can be written. It is a sample since the purpose is to
give an idea about how it can be implemented and perform, rather than be
used on general production setups. Especially, it supports only two tiers
memory setup having only one CPU-attached NUMA node.
