Add comments for multidim tensor factory limitations, and rename ListInitTensor for better clarity (#26756)
Summary:
This PR includes the following improvements:
1. Add comments for limitations of the multidim tensor factory function `torch::tensor(...)`, noting the fact that `torch::tensor({})` and mixed data type such as `torch::tensor({{bool, 2.0}})` are not supported at the moment. (I will also update https://pytorch.org/cppdocs/notes/tensor_creation.html to include usage examples for the multidim tensor factory function `torch::tensor(...)`)
2. Rename `ListInitTensor` to `InitListTensor`, for better naming consistency.
This addresses reviews in https://github.com/pytorch/pytorch/pull/26210. I will work on a separate PR to move the factory function to `at::`.
