Remove bugged and typically slower `minimum`/`maximum` method (#58267)
This method intends to be a SIMD-able optimization for reductions with
`min` and `max`, but it fails to achieve those goals on nearly every
architecture. For example, on my Mac M1 the generic implementation is
more than **6x** faster than this method.
Fixes #45932, fixes #36412, fixes #36081.
