Arm backend: Match arg ranks for min/max ops (#16181)

- Int32 clamp is decomposed into min/max, but input_tensor and
min_arg/max_arg can end up with different ranks (e.g. (1,) vs ()) after
subsequent passes. This violates the TOSA requirements for TOSA.MINIMUM
and TOSA.MAXIMUM in the node visitors.
 - Fix this by matching the input ranks in MatchArgRanksPass
