Pepper Flash settings integration: implement "deauthorize content licenses".

A few notes about PepperFlashSettingsManager:
- It doesn't re-establish a channel for each request. It might seem unnecessary at this point. But that is needed for implementing content settings (camera/mic and peer networking), which requires more interactions with the broker process.
- Similarly, the support of multiple in-flight requests isn't very useful for deauthorizing content licenses, but that is useful for content settings, e.g., sending multiple GetPermissionSettings requests for different setting types.
