Code Review

This pull request removes code related to PanguProMoEV1, which is no longer supported. The changes are straightforward and consist of deleting the TokenDispatcherWithMoge class and removing conditional logic specific to PanguProMoE in AllGatherCommImpl and NPUModelRunner. The modifications are consistent with the goal of cleaning up deprecated code. I've reviewed the changes and they appear correct and complete within the provided context. I did not find any high or critical issues.
