MAINTAINERS: rename DAMON section

DAMON section name is 'DATA ACCESS MONITOR', which implies it is only for
data access monitoring.  But DAMON is now evolved for not only access
monitoring but also access-aware system operations (DAMOS).  Rename the
section to simply DAMON.  It might make it difficult to understand what it
does at a glance, but at least not spreading more confusion.  Readers can
further refer to the documentation to better understand what really DAMON
does.
