`read_zero_byte_vec` refactor for better heuristics

Fixes #9274

Previously, the implementation of `read_zero_byte_vec` only checks for the next statement after the vec init. This fails when there is a block with statements that are expanded and walked by the old visitor.

This PR refactors so that:

1. It checks if there is a `resize`	on the vec
2. It works on blocks properly

e.g. This should properly lint now:

```
    let mut v = Vec::new();
    {
        f.read(&mut v)?;
        //~^ ERROR: reading zero byte data to `Vec`
    }
```
