libcamera: v4l2_videodevice: Empty the V4L2 buffer cache on streamOff()
When streamOff() is called, ensure the cache entries for the remaining queued
buffers are freed since this will not happen via the dequeueBuffer() mechanism.
Additionally, add a V4L2BufferCache::isEmpty() function and assert that the
cache is empty at the end of the streamOff() call.
