[WeakMemoryCache] Revert Field-Trial: Make Reference from MemoryCache to Resource weak

This is partial revert of
https://codereview.chromium.org/1915113005.

The modifications in MemoryCache are reverted before going to beta because it
might be not so stable, while other field-trial related changes are kept
because I'm planning further experiment in the next milestone.

I assume we keep the weakMemoryCache flag for now in order to do further
iteration after branch cut-- is that right?
