Convert CefCookieManagerImpl to use CefBrowserContext::Getter.

Browse Source 
With this change CefCookieManagerImpl no longer keeps a reference to the
originating CefRequestContextImpl. This means that the CefRequestContextImpl
can be destroyed if all other references are released while the
CefCookieManagerImpl exists. If CefRequestContextImpl destruction results in
the underlying CefBrowserContext being destroyed then the CefCookieManagerImpl's
reference to that CefBrowserContext will be invalidated.

This is the same ownership model introduced with CefMediaRouterImpl in the
previous commit.
