Existing CefBrowserContext functionality is now split between CefBrowserContext and AlloyBrowserContext. Runtime implementations of CefBrowserContext will provide access to the content::BrowserContext and Profile types via different inheritance paths. For example, the Alloy runtime uses ChromeProfileAlloy and the Chrome runtime uses ProfileImpl. This change also renames CefResourceContext to CefIOThreadState to more accurately represent its purpose as it no longer needs to extend content::ResourceContext.
