Please restore the enums in this file. There's an easily missed comment about 7000 lines above that says we shouldn't remove enum entries for removed flags:

See also the "Flags histograms" section in the README which has instructions for how this file should be updated:

        Remove kComputePressureBreakCalibrationMitigation flag

        This flag has been enabled by default since November 2023, so
