P0009: Same interface for `is_always_strided`

[tpadioleau]

The mapping for layout_stride has a strides() member function to retrieve at once all the strides whereas layout_left and layout_right do not. I was wondering if it could be possible to require for all mappings satisfying is_always_strided() to implement both stride(size_t) and strides() ? This could ease writing generic code with a strided_layout concept.

Considering where the design process is and the time limit for getting into C++23 we would need to do this via a national body comment.

If it does not fit for C++23 it is not a big deal.
