WT-2954 Evict pages that exceed memory_page_max even if the transaction ID is stuck (#3088)
Try to evict pages that exceed memory_page_max even if the transaction ID isn't increasing.
Workloads that insert large values checking only for the transaction ID moving forward can lead to very large in-memory pages. Allow the page to exceed the split size, but not the configured maximum.
Skipping such pages is a performance optimization - allow the optimization to work as long as pages are between split size and maximum size.
Also don't require so many entries on a leaf page to trigger a split when there are large values.
