libcamera: controls: initialise control info to ControlTypeNone by default

Browse Source 
The default ControlInfo constructor allows partially initialising the
min/max/def values. Uninitialised values are assigned to 0 by default.
This implicit initialisation makes it impossible to distinguish between
an uninitialised and an explicitly 0-initialised ControlValue.

Default construct the ControlValue in the ControlInfo default contructor to
explicitly represent uninitialised values by the ControlTypeNone type.
