7e84448a - Address review: consistent CPU/CUDA empty-set behavior and extended tests

Address review: consistent CPU/CUDA empty-set behavior and extended tests - Fix ReduceMean comment: clarify 0 fill is for CPU/CUDA consistency (ReduceAggregatorMean inherits ReduceAggregatorSum::fill_for_empty_set) - Add ReduceMin_EmptyTensor_DefaultAxes test (reduce-all, scalar output) - Add ReduceMin_EmptyTensor_DefaultAxes_KeepDims test - Add ReduceMean_EmptyTensor_DefaultAxes test - Update test header comment: ReduceMean → 0 (not NaN) - All tests are EP-independent (no #ifdef USE_CUDA guards) Signed-off-by: Justin Chu <justinchu@microsoft.com>
