[primTorch] Adds broadcast_to, column_stack references (#78416)
1. Added references for the two ops;
2. Inherited original operators' OpInfo tests;
TODO for future PR:
adding primTorch references for `dsplit` and `dstack`. <- Those two should use `atleast_3d` which is in a different packet right now.
