MLBEDSW-11309: Add tensor readers behavioral test
Also fixes bug found by test in InsertCopyOpAfterTensor. If the pointer to op->Input(tensorusage)->tensor is used as parameter ifm, the ifm tensor can be updated by ConnectInput during interation over ifmReaders, resulting in incorrect comparison between consIfmConn->tensor.get() == ifm.get().
