libcamera: Add a C++20-compliant std::span<> implementation

C++20 will contain a std::span<> class that provides view over a
contiguous sequence of objects, the storage of which is owned by some
other object.

Add a compatible implementation to the utils namespace. This will be
used to implement array controls.
