The `vx_array::new(Arc::new(x.into_array()))` pattern double-wraps arrays since `into_array()` already returns `Arc<dyn DynArray>`. With the new `apply(self: Arc<Self>)` signature, this breaks downcasting because the concrete type behind the trait object becomes `Arc<dyn DynArray>` instead of the actual encoding type.

This change breaks the array.apply(expr) method however making it take the ArrayRef instead.
This fixes a huge perf regression in apply that clones the inner Array not the ArrayRef
