Fix dynamo use of list[int] in graph break (#145554)

Summary:
This reintroduces the change backed out by #145393 and fixes the underlying problem.

Although using a BuiltinVariable was better than nothing when we saw a GenericAlias it had problems if there was a graph break and we had to reconstruct the original python code which BuiltinVariable did as a simple `list` instead of a `list[int]`.

This changes it to use a TypingVariable instead and then teaches TypingVariable how to reconstruct.
