[FEA] Add support for mdspan

[cliffburdick]

mdspan is an upcoming feature in C++23 with two main changes:

1. operator[] for multi-dimensional arrays
2. Indexing and types for multi-dimensional arrays

While 1 requires a new C++ compiler, 2 has been included the CCCL recently. For this feature we can add partial support for the second part by taking in mdspan types into make_tensor calls to translate to what we have.
