damos->ops_filters has introduced to be used for operations layer
handled filters. But DAMON kernel API callers can put any type of DAMOS
filters to any of damos->filters and damos->ops_filters. DAMON ABI
users have no way other than still using only damos->filters. Update
damos_add_filter(), which should be used by API callers to install DAMOS
filters, to add core layers and operation layer handled filters to
->filters and ->ops_filters, respectively. The change is applied to
both API callers and ABI users since ABI users use the API internally.
