As requested in #33599 . This adds a shorthand for
cumsum!(A; dims)andcumprod!(A;dims), which are equivalent tocumsum!(A, A; dims)andcumprod!(A, A;dims).I checked that the called accumulate functions
accumulate_pairwise!,_accumulate!,_accumulaten!, and_accumulate1!read each element before writing to it so that the casecumsum!(B, A; dims)B===Ais alias-safe for sum and product.This also adds changes to the docstrings and adds tests that check the new single-argument methods.
