V4L2 Controls support a wide variety of types not yet supported by the ControlValue type system. Extend the libcamera ControlValue types to support an explicit 16 bit unsigned integer type, and map that to the corresponding V4L2_CTRL_TYPE_U16 type within the v4l2_device support class. It's used on some camera metadata that is of length 16-bits, for example JPEG metadata headers.
