Add support for setting V4L2_CID_VBLANK appropriately when setting V4L2_CID_EXPOSURE. This will allow adaptive framerates during viewfinder use cases (e.g. when the exposure time goes above 33ms, we can reduce the framerate to lower than 30fps). The minimum and maximum frame durations are provided via libcamera controls, and will prioritise exposure time limits over any AGC request. V4L2_CID_VBLANK is controlled through the staggered writer, just like the exposure and gain controls.
