First problem solved by adding quantize of scalar_tensor: The where.self operator got a scalar_tensor input which was not quantized. This happened since the where.self quantization annotator uses the parent specs, which in this case where non-existing. Adding the quantization of scalar_tensor sorts this out.

Secondly when quantizing scalar_tensor the following assert triggers:
expecting kwargs for aten op IR to be empty
Hence setting scalar_tensor kwargs to {}.

Finally trying to quantize -inf fails for scalar_tensor nodes fails Fix it by adding the pass from qnn backend to replace -inf/inf. Hence adding new pass ReplaceInfValues.
