Also servicified ClearNetworkErrorLogging as it's extremely similar
logic.

Moved the clearing on DATA_TYPE_COOKIES to BrowsingDataRemoverImpl as it
is not chrome-specific, and left the clearing on DATA_TYPE_HISTORY in
ChromeBrowsingDataRemoverDelegate. Especially good cleanup for Reporting
data as the two cases were split into two independent Clear... methods
in NetworkContext.
