Docs/admin-guide/mm/damon/usage: use a list for 'state' sysfs file input commands
There are eight command inputs for 'state' DAMON sysfs file, and those are verbosely explained in multiple paragraphs. It is not easy to find explanation of specific command, and getting whole picture of supported commands. Replace the paragraphs with a list.

+- ``on``: Start running.
