libcamera: v4l2_controls: Remove V4L2ControlInfo type field

Browse source 
The V4L2ControlInfo type field stores the V4L2 control type. It partly
duplicates the V4L2ControlInfo id().type() that stores the corresponding
libcamera control type. The two fields are not strictly identical, but
having two types doesn't provide us with any extra value. As this is
confusing, remove the V4L2ControlInfo type field.
