refactor(ext/node): enforce interior mutable for NodePermissions to remove clones (#18831)

We can make `NodePermissions` rely on interior mutability (which the
`PermissionsContainer` is already doing) in order to not have to clone
everything all the time. This also reduces the chance of an accidental
`borrow` while `borrrow_mut`.
