Implement getMinimalSupportedVersion for all NameDiffs (#81374) (#81408)

This removes the default implementation of `getMinimalSupportedVersion` and implements it in all `NameDiffs` implementations. The default implementation was rather broad, `minimumIndexCompatibilityVersion` as the index compatibility are wider than our wire compatibility. Having a default implementation also had the implementors forget about adjusting the wire compatibility to the correct version.
