libcamera: v4l2_controls: Remove V4L2ControlInfo::size()

Browse source 
We don't support V4L2 compound controls, the size field is thus unused.
Remove it to ease merging of the libcamera and V4L2 control info
classes. Support for array controls can then be added later on top, and
would be useful for libcamera controls too.
