Add OpInfo for torch.linalg.tensorsolve (#68810)
Summary:
This PR adds an OpInfo entry for tensorsolve function.
The keyword argument is different from NumPy so a lambda function is needed to be passed to `ref=`.
I had to change the dtypes for `test_reference_testing` because NumPy does computation internally using double for all linear algebra functions and maybe for some other functions. Using `torch.float64` and `torch.complex128` is more reliable for NumPy comparisons.
