Adds three new off-by-default columns to the task manager to track WebCore caches

These values are currently exposed via about:histograms/WebCoreCache. This change allows for users to monitor the cache sizes in real-time broken out by renderer.

TEST=Open task manager, right click on chrome, select columns, observe that they update along with browsing.
