Adds the following attribute to
`sui_graphql_rpc::types::object::Object`:
```rust
/// Optional root parent object version if this is a dynamic field.
///
/// This enables consistent dynamic field reads in the case of chained dynamic object fields,
/// e.g., `Parent -> DOF1 -> DOF2`. In such cases, the object versions may end up like
/// `Parent >= DOF1, DOF2` but `DOF1 < DOF2`. Thus, database queries for dynamic fields must
/// bound the object versions by the version of the root object of the tree.
///
/// Essentially, lamport timestamps of objects are updated for all top-level mutable objects
/// provided as inputs to a transaction as well as any mutated dynamic child objects. However,
/// any dynamic child objects that were loaded but not actually mutated don't end up having
/// their versions updated.
root_version: Option<u64>,
```
I tried making sure that this attribute is set correctly wherever an
`Object` is created.
There's one scenario which still isn't covered: if the GQL query is
rooted at a DOF, something like
```graphql
query DynamicFields($parent: SuiAddress!, $version: Int, $after: String) {
object(address: $parent, version: $version) {
dynamicFields(/* ... */) {
// ...
}
}
}
```
where `$parent` is a DOF's object id, then the server has no way to know
the root object's version. Instead, we will use the rooting object's version, even if it is a nested child object.
New tests `immutable_dof.move` and `nested_dof.move`.
