libcamera: controls: Allow passing an std::initializer list to set()
For array controls, the ControlList::set() function takes a value as a type convertible to Span<T>. This allows passing an std::array or an std::vector in addition to an explicit Span, but doesn't accept an std::initializer list as Span has no constructor that takes an initializer list. Callers are thus forced to create temporary objects explicitly, which isn't nice. Fix the issue by providing a ControlList::set() function that takes an std::initializer_list, and convert it to a Span internally.
