Summary

This PR enables the keyword arguments of liger functional #368.

1. Warp the Liger Operator Functions (torch.autograd.Function) with an extra layer that can take key word arguments.
2. For each of the liger functions, updating its unit test function test_{operator_name}.py::test_correctness_functional to reflect that keyword args can be accepted.

Testing Done

• Hardware Type: A10G
• run make test to ensure correctness
