This PR generalizes the MinMax monotonic optimizer to support SegmentMax, UnsortedSegmentMax and ArgMax operations.

This is a rebased version of #25330 which was reverted due to #25330 (comment).

This PR surfaces a bug in the existing algorithmic optimizer which is fixed in #25535, thus #25535 should be merged prior to this.

#25535 has been merged and CI errors seem to be unrelated. This should be good to go now.
