cfc0ff16 - Renaming: MultiLabelMarginLossFuncOptions -> MultilabelMarginLossFuncOptions, MultiLabelSoftMarginLossFuncOptions -> MultilabelSoftMarginLossFuncOptions (#35163)

Renaming: MultiLabelMarginLossFuncOptions -> MultilabelMarginLossFuncOptions, MultiLabelSoftMarginLossFuncOptions -> MultilabelSoftMarginLossFuncOptions (#35163) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/35163 This PR is BC-breaking in the following way: Renaming: - `torch::nn::functional::MultiLabelMarginLossFuncOptions` -> `torch::nn::functional::MultilabelMarginLossFuncOptions` - `torch::nn::functional::MultiLabelSoftMarginLossFuncOptions` -> `torch::nn::functional::MultilabelSoftMarginLossFuncOptions` Reason for renaming: to be consistent with the corresponding functional name after camel case to snake case conversion (e.g. the `multilabel_margin_loss` functional should use `MultilabelMarginLossFuncOptions` as options) Test Plan: Imported from OSS Differential Revision: D20582598 Pulled By: yf225 fbshipit-source-id: 0f5bdb8249d901b310875a14320449a2fdfa8ecd
