Michael Cahill 71c8bd736c WT-2902 Track per-tree the efficiency of eviction walks. (#3036) ...

Some workloads create "deserts" within a tree where no good eviction
candidates can be found (e.g., zipfian distributions, append-only
workloads, etc.).  Rather than walking all the way through such
regions, give up and try in the opposite direction next time.

Also add a statistic for the eviction empty score.
