Message: WT-2673 Stop automatically increasing memory page max (#2760)

We used to ensure it was at least 50 times the leaf page size, enhancements to how we split pages mean that's no longer necessary.

While reviewing the code adjust the maximum page size allowed to ten percent of the cache size. It is more reasonable for workloads with multiple tables, and should only be relevant when applications configure tiny caches.

This commit replaces a number of previous backports with the original
change, so some of the tickets listed below may have been resolved in
previous versions already as a backport to the v3.2 branch. For example,
SERVER-24580 includes change a63e21b8 as a cherry-pick of 1f4aaa44, but
this commit replaces that change with 1f4aaa44 itself.
