Replaces v4. The important changes are:
- Split the testcase into one per layout.
- Fixed __slice_mapping and moved tests from `*_neg.cc` to
generic.cc using concepts.
- Make _BufferSize a regular parameter.
- Fixed bug in __substrides.
I didn't change the logic for _S_is_unpadded_submdspan, because
it exactly matches the text of the standard; and this way there's to
fear that __slice_kinds[0] is invalid.
