Removed create_golden_Tensor, created "safe" custom Constructor

[vprajapati-tt]

• PR closes Python/Passes.cpp - create_golden_tensor has unsafe pointer reference #2027
• Changes container for GoldenTensor in Python to be a shared_ptr, ensuring data is maintained and not copied.
• Uses GoldenTensor custom constructor instead of create_golden_tensor.
• Creates copy of supplied data_ptr (size of data must also be provided, example in ttir_builder.py) and stores within GoldenTensor object.

@vroubtsovTT I tried to make the vector a unique_ptr but pybind kept trying to keep a copy of it. Let me know if you have any thoughts on this and what I could've changed / done better. Thanks :)

That may have been a sign that you were on the right track. Somebody wanted to copy your struct and couldn't because std::unique_ptr member fields aren't copyable -- this failed as it should. But a std::unique_ptr member will be move-copyable... you should try to make your struct move-copyable by adding

MyStruct(MyStruct && rhs) = default;

(and/or implementing such a move constructor if default doesn't work).
