Unsoundness: `ListVector` is missing a lifetime specifier, allowing use-after-free

[t1mlange]

Hi,

the following safe Rust snippet causes a use-after-free using your library:

use duckdb::core::{DataChunkHandle, LogicalTypeHandle, LogicalTypeId};

fn main() {
    let mut vec;
    {
        let list_type = LogicalTypeHandle::list(&LogicalTypeId::Integer.into());
        let chunk = DataChunkHandle::new(&[list_type]);
        chunk.set_len(1);

        vec = chunk.list_vector(0);

        vec.set_entry(0, 0, 2);

        println!("{:?}", vec.get_entry(0));
    }
    println!("{:?}", vec.get_entry(0));
}

$ RUSTFLAGS="-Zsanitizer=address" cargo r --release  --target x86_64-unknown-linux-gnu
(0, 2)

To ensure that the non-owned vector pointer within ListVector is valid, you can either

1. refcount the owner within the ListVector, ensuring safety at runtime
2. add an actual reference to the owner in the structure (probably not required)
3. add a phantom lifetime PhantomData<&'a DataChunkHandle>, which only exists during borrow-checking

If I'm not mistaken FlatVector, ArrayVector and StructVector need the same treatment.

Kind regards
Tim
