PeriodIndex comparisons turn out to be easier to move than the others (though partly because ATM they are broken: #21793), so this moves them over first.
Following that, most of the remaining PeriodArray arithmetic methods require
shift, which in turns requires the constructors, so I went ahead and implemented those in PeriodArrayMixin. Still holding off on TimedeltaArray and DatetimeArray constructors.Found a few more things that could be harmlessly moved and some docstring fixups.
