  [iOS] Expand Web process cache capacity on some devices

Reviewed by Chris Dumez.

Expand Web process cache capacity on some iOS devices. Devices are not normally reporting memory capacity in GB multiples. This patch
is using a more fine grained computation of the cache size, instead of basing it on GB multiples. This will effectively enable the Web
process cache for some devices. We still have the upper limit of 10 Web processes in the cache on iOS, so the cache will never be
bigger than that. On memory pressure, we still shut down the processes in the Web process cache. I have been validating this change on
a device affected by this patch, and so far the testing looks good.
