mm/damon/core: add cleanup_target() ops callback

Browse source

Some DAMON operation sets may need additional cleanup per target.  For
example, [f]vaddr need to put pids of each target.  Each user and core
logic is doing that redundantly.  Add another DAMON ops callback that will
be used for doing such cleanups in operations set layer.
