mm: shrinker: Add new stats for .to_text()
Add a few new shrinker stats.
number of objects requested to free, number of objects freed:
Shrinkers won't necessarily free all objects requested for a variety of
reasons, but if the two counts are wildly different something is likely
amiss.
.scan_objects runtime:
If one shrinker is taking an excessive amount of time to free
objects that will block kswapd from running other shrinkers.
