Simplify the implementation of iterators over slices of ZSTs
Currently, slice iterators over ZSTs store `end = start.wrapping_byte_add(len)`. That's slightly convenient for `is_empty`, but kinda annoying for pretty much everything else -- see bugs like 42789, for example. This PR instead changes it to just `end = ptr::invalid(len)` instead. That's easier to think about (IMHO, at least) as well as easier to represent.
