Add array_windows fn This mimicks the functionality added by array_chunks, and implements a const-generic form of `windows`. It makes egregious use of `unsafe`, but by necessity because the array must be re-interpreted as a slice of arrays, and unlike array_chunks this cannot be done by casting the original array once, since each time the index is advanced it needs to move one element, not `N`. I'm planning on adding more tests, but this should be good enough as a premise for the functionality. Notably: should there be more functions overwritten for the iterator implementation/in general? ~~I've marked the issue as #74985 as there is no corresponding exact issue for `array_windows`, but it's based of off `array_chunks`.~~ Edit: See Issue #75027 created by @lcnr for tracking issue ~~Do not merge until I add more tests, please.~~ r? @lcnr
