DAMON_STAT doesn't provide the pid of its kdamond, unlike DAMON_RECLAIM
and DAMON_LRU_SORT.  This makes user-space management of DAMON_STAT
unnecessarily complicated.  Provide the information via a new parameter,
namely kdamond_pid, and document it.

Changes from RFC
- rfc: https://lore.kernel.org/20260414053742.90296-1-sj@kernel.org
- Fix damon_kdamond_pid() failure handling.
