a68c5249 - Use F::*FuncOptions for embedding/embeddingbag functionals (#29673)

Use F::*FuncOptions for embedding/embeddingbag functionals (#29673) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/29673 Following https://github.com/pytorch/pytorch/pull/29364 and https://github.com/pytorch/pytorch/pull/29404, this PR makes `F::EmbeddingFuncOptions` and `F::EmbeddingBagFuncOptions` separate classes from `torch::nn::EmbeddingOptions` and `torch::nn::EmbeddingBagOptions`, so that it's easier to enforce that arguments such as `num_embeddings` and `embedding_dim` are required for `torch::nn::EmbeddingOptions` and `torch::nn::EmbeddingBagOptions`.
