Mac AVFoundation/QTKit: delay DeviceMonitorMac startup to first GetUserMedia.
Currently DeviceMonitorMac is constructed from BrowserMainLoop in the
first compasses of Chrome bringup. DeviceMonitorMac creates either a
QTKitMonitorImpl or a AVFoundationMonitorImpl, that immediately
starts observing the system capture devices. This monitoring is
not needed until the user actively starts operating the devices,
that happens in MediaStreamManager.
This CL adds a method StartMonitoring() to DeviceMonitorMac that is
exercised from MediaStreamManager::StartMonitoring().
The performance regression in bugs 349616 and 348020 affects only
AVFoundation, but both implementations would benefit from a delayed
startup.
Tested locally via using --[enable/disable]-avfoundation, connecting
and disconnecting devices etc.
BUG=288562, 349616, 348020
