The attribute was added and used in openxla/xla@cf3dfa9 but rolled back in openxla/xla@5542ebc since it broke TPU tests. However, HLO text generated between these two commits have the 'mode' attribute. So parse and ignore it for now to not break parsing such HLOs. In the future, once the TPU tests are fixed, the full commit will be rolled forward. Like in the original commit, I move the CollectiveOpGroupMode to it's own file to keep the parsing logic the same as the original commit. PiperOrigin-RevId: 786115058
