COMPMID-2637 [CL] fix broadcast pixel-wise multiplication with 5D tensors

Broadcast pixel-wise multiplication with 5D tensors is fixed
by adding information whether a dimension has been broadcasted
to compute correct start offset when adding 3D tensor argument.
The testcase that failed is added to the validation test suite.
