crrev.com/c/5448942 added a restriction on the reduction ops (including argMin/argMax) that the rank of the input tensor must be greater than zero. In webmachinelearning/webnn#681, @fdwr points out that 0-D (scalar) reductions are fine, it's just a no-op. Per that discussion, this removes a restriction. There are already WPT cases for argMin/argMax (although they fail for other reasons); cases are added for the plethora of reduction ops (which also fail for other reasons).
