Refactor VM field access to use Rc clones

The VM's field access logic has been refactored to clone `Rc` pointers
for addresses and field identifiers. This change aims to improve
efficiency by avoiding unnecessary dereferencing and copying of values
when accessing fields within records and objects.

Additionally, the `Value::Object` handling in `BoundKind::GetField` has
been refined to more explicitly manage `RecordSeries` and `StreamNode`
types, ensuring that field access is handled polymorphically and
efficiently without copying underlying data structures.
