What does this PR do?

Background: This PR addresses a bug related to the handling of torch.special operators, discovered during the development of PR #976.

torch.special operators has __name__ in the format special_opname, requiring extraction of the actual opname. Similar issues occur with torch.linalg and torch.fft operators.

In this PR:

• Add function _get_torch_function_name to infer the python call name from the torch module and function
• Add support for auto-registration of torch.linalg and torch.fft operators and the tests

Hi @t-vi @IvanYashchuk , we could discuss further if https://github.com/Lightning-AI/lightning-thunder/pull/976 is necessary, this is a bug I found along the way, so I split it out and we could review this first. Testing results:
