[jit][edge] Pass through dynamic type for DictType. (#74025)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/74025
When users are trying to inspect IValues out of the Lite Interpreter, dynamic types are still attached, therefore torch::jit::toPyObject will fail on these dynamic types while converting dictionary keys.
We should just let dynamic types pass through under this corner case since they won't be used by anything later.
