qcam: main_window: Replace start and stop actions with a toggle action
The main window toolbar contains a start button and a stop button. This allows starting an already started camera (which is currently not handled and results in an error) or stopping an already stopped camera. Replace the two actions with a single start/stop toggle action, preventing UI misuse and reducing confusion.
