      Based on the investigation done in WT-9121, the current walk position is dropped in two cases: (a) eviction pass ends, (b) __evict_walk_tree is unable to find evictable pages.

      Improve the walking logic so that the scanning efficient and spans the whole tree.

      All potential solutions should go through performance tests.
