AVF: Don't apply settings if the camera is not active yet
In macOS, a capture session can still automatically configure the capture
format after you make changes.
If frame rates are applied to the capture device and the camera
is still not active, these rates will be overridden by old values
when the capture session will be started.
For this purpose lockForConfiguration is currently used within startRunning method
of capture session. But in case if the settings are already applied to the capture device,
we don't call lockForConfiguration within starting of the capture session
(since it is needed to be called only when the settings have been changed).
Suggesting to postpone setting of the format (to the capture device) until
the camera is started.
This will lead to apply settings before startRunning method with proper configuration lock.
Fixes: QTBUG-81048
