Subject: [PATCH] Introduce way to check if there is an off-the-record session
 active.

Introduce a new function IsOffTheRecordSessionActive() that returns
true if there is an off-the-record session active. It is equivalent
to chrome::IsOffTheRecordSessionActive() but for Chrome on iOS.

Implement it via ChromeBrowserProvider.
