[ET-VK] Serialize list types from function args

In #2271, we already added
- IntList
- DoubleList
- BoolList
- ValueList

to the schema and the runtime's Value class. Their serialization was incomplete missing two components:
1. Receiving a list in `torch.fx.Node.args`.
2. Receiving a non-tensor in `torch.fx.Node`.

This change completes #1.


Also, this change fixes a bug where values type `bool` matches both types `bool` and `int` and hence were being added twice.

If our type support grows more complex, we can consider using our own types similar to the core Executorch runtime: https://github.com/pytorch/executorch/blob/689796499024fc4a133318d707f4c10db73da967/exir/emit/_emitter.py#L158-L166
