fix: `manual_memcpy` wrong indexing for multi dimensional arrays

fixes: #9334

This PR fixes an invalid suggestion for multi-dimensional arrays.

For example,
```rust
let src = vec![vec![0; 5]; 5];
let mut dst = vec![0; 5];

for i in 0..5 {
    dst[i] = src[i][i];
}
```

For the above code, Clippy suggests `dst.copy_from_slice(&src[i]);`, but it is not compilable because `i` is only used to loop the array.
I adjusted it so that Clippy `manual_memcpy` works properly for multi-dimensional arrays.
