libcamera: span: Make constructors explicit as required by C++20
The C++20 std::span class, after which Span is modelled, specifies four constructors as explicit when extent is not dynamic_extent. Align our implementation with those requirements. A careful reviewer may notice that this change addresses five constructors, not four. The reason is that the two constructors taking Container and const Container parameters are not specified in C++20, which uses a single constructor taking a range parameter instead. As ranges are not available in C++17, the Container constructors are our best effort at providing a similar feature.
