This patch completes the C++23 part of <mdspan> and must be applied after the default_accessor patch.
A question for review: Should we add additional tests, that check that the implementation works with custom layouts, accessors and data_handle_types? It's shared now to allow developers working on linear algebra to proceed. I'll likely keep working on the tests. Therefore, until default_accessor has been merged a detailed review might be premature.
