Remove deprecated ShadowNode type aliases (#55687)

Summary:

## Changelog:
[General] [Breaking]: Removing deprecated type aliases. Use the type directly.

Remove deprecated type aliases from ShadowNode that were scheduled for deletion in 0.84:
- `ShadowNode::Shared` → use `std::shared_ptr<const ShadowNode>`
- `ShadowNode::Weak` → use `std::weak_ptr<const ShadowNode>`
- `ShadowNode::Unshared` → use `std::shared_ptr<ShadowNode>`
- `ShadowNode::ListOfShared` → use `std::vector<std::shared_ptr<const ShadowNode>>`
- `ShadowNode::ListOfWeak` → use `std::vector<std::weak_ptr<const ShadowNode>>`
