* refactor reduce kernel - Rename Reduce kernel as per convention - Move kept_dim and reduce_dims from runtime to compile-time parameters - Update Reduce2dProblem template to include KeptDim, ReduceDims, and Rank - Remove IsSupportedArgument validation function as it's unnecessary. Not using the GuaranteedLastDimensionVectorStride while making tensor view or descriptor which removes the bounds enforced earlier. We still calculate and use vector size. - Update reduce example to demonstrate NCHW->NHW reduction with non-contiguous support - Update tests Kernel now handles both contiguous and non-contiguous memory layout. * fix compile errors
