Delete duplicate definition of DequantizeConstantTensor in model_builder.cc: it already exists in model_builder_helper.h. It was not generating a compiler error for multiple definition because this is a function template.

It actually had a slightly different implementation, what is undefined behavior. Keep the version that had recent updates.
