replace strided_slice with extent_slice

[nmm0]

This replaces strided_slice with extent_slice as strided_slice was renamed in the C++26 standard. This currently does not also add range_slice which will be done in another PR.

Currently this deprecates use of strided_slice but I am open to discussing that.

Hm, I don't think this is right. extent_slice also changed the meaning of "extent" didn't it?

I might be mixing up things but at least in https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2026/p3982r2.html it specifies extent_slice is just a rename of strided_slice, and indeed the wording in that paper only has the range_slice change.

Ah nvm I misread the wording it had an additional change to extents

We should have a test somewhere which is actually sensitive to the change you just did.

The current test should check it, as in I had to adjust the test after the change to just use the extent or it would not pass. Unless you had something specific in mind?

Ah ok found it.

I tested a Serial build in Kokkos and it passed.

You tested against Kokkos, right?
