optimize zipping over array iterators

Fixes #115339 (somewhat)

the new assembly:

```asm
zip_arrays:
        .cfi_startproc
        vmovups (%rdx), %ymm0
        leaq    32(%rsi), %rcx
        vxorps  %xmm1, %xmm1, %xmm1
        vmovups %xmm1, -24(%rsp)
        movq    $0, -8(%rsp)
        movq    %rsi, -88(%rsp)
        movq    %rdi, %rax
        movq    %rcx, -80(%rsp)
        vmovups %ymm0, -72(%rsp)
        movq    $0, -40(%rsp)
        movq    $32, -32(%rsp)
        movq    -24(%rsp), %rcx
        vmovups (%rsi,%rcx), %ymm0
        vorps   -72(%rsp,%rcx), %ymm0, %ymm0
        vmovups %ymm0, (%rsi,%rcx)
        vmovups (%rsi), %ymm0
        vmovups %ymm0, (%rdi)
        vzeroupper
        retq
```

This is still longer than the slice version given in the issue but at least it eliminates the terrible  `vpextrb`/`orb` chain. I guess this is due to excessive memcpys again (haven't looked at the llvmir)?

The `TrustedLen` specialization is a drive-by change since I had to do something for the default impl anyway to be able to specialize the `TrustedRandomAccessNoCoerce` impl.
