COMPMID-3324: Allow in-place mutation on nodes with separate multiple inputs

The current implementation of the in-place mutator is limited by the
assumption that each node only produces one output and therefore all
its output edges represent the same tensor. This means that doing
in-place computations on it, would modify the input of other nodes.

However, this is not the case for operators like split, which creates N
different tensors, one for each output edge.

This patches relaxes this limitation by checking whether the tensor
related to a specific output edge is the same as any of the other edges.
If this is the case, then in-place computation cannot be done.
