libcamera: controls: Decouple control and value type in ControlList::set()
The ControlList::set() method takes a reference to a Control<T>, and requires the value to be a reference to T. This prevents the set() method from being used with value types that are convertible to T, and in particular with std::array or std::vector value types when the Control type is a Span<> to support array controls. Fix this by decoupling the control type and value type in the template parameters. The compiler will still catch invalid conversions, including cases where the constructor of type T from the value type is explicit.
