libcamera: control_serializer: store/load all ControlValue types

The min/max/def ControlValue of a ControlInfo can take arbitrary types that
are different from each other and different from the ControlId type.
The serialiser serialises these ControlValue separately by their type but
does not store the type. The deserialiser assumes that ControlValue types
match the ControlId type. If this is not the case, deserialisation will try
to deserialise values of the wrong type.

Fix this by serialising each of the min/max/def ControlValue's ControlType
and storing it just before the serialised ControlValue.
