mm/damon: rename damon_pageout_score() to damon_cold_score()

In the beginning there is only one damos_action 'DAMOS_PAGEOUT' that need
to get the coldness score of a region for a scheme, which using
damon_pageout_score() to do that.  But now there are also other
damos_action actions need the coldness score, so rename it to
damon_cold_score() to make more sense.
