[GTK] webkit_set_cache_model is not turning the cache off
https://bugs.webkit.org/show_bug.cgi?id=118345

Reviewed by Gustavo Noronha Silva.

Our documentation says that WEBKIT_CACHE_MODEL_DOCUMENT_VIEWER
disables the cache completely, but we are only setting the cache
capacities to 0. Cache capacities are not checked when resources
are added to the cache, but when it's pruned. To disable the cache
we need to call MemoryCache::setDisabled explicitly.

* webkit/webkitglobals.cpp:
(webkit_set_cache_model): Disable the cache when min dead, max
dead and total capacities are all set to 0.
