service/cam: Implement Vsync interrupt callbacks
According to HW tests, this vsync event is signaled for activated cameras at about the same frequency as the frame rate. The last 5 vsync timings are recorded (in microseconds) and can be retrieved with the service function.

Also, corrected the default frame_rate to 15, according to HW test.

This should fix the missing camera images in certain games.
