Currently ctrl + overview calls
CaptureModeController::CaptureScreenshotsOfALlDisplays() but this does
not record any metrics.

This CL changes it so when CaptureScreenshotsOfALlDisplays() is called,
it records to Ash.CaptureModeController.EntryPoint and
Ash.CaptureModeController.CaptureConfiguration.
