API转换21-41

单测PR PaddlePaddle/PaConvert#320

21	torch.broadcast_tensors	paddle.broadcast_tensors	已有文档验证无误
22	torch.broadcast_shapes	paddle.broadcast_shape	已有文档验证无误
23	torch.can_cast		功能缺失
24	torch.utils.data.DataLoader	paddle.io.DataLoader	已有文档验证无误
25	torch.nn.Threshold	paddle.nn.ThresholdedReLU	已有文档和单测，paddle不支持 value 参数，value参数在torch中为必填
26	torch.nn.functional.threshold	paddle.nn.functional.thresholded_relu	已有文档和单测，paddle不支持 value 参数，value参数在torch中为必填
27	torch.nn.Transformer	paddle.nn.Transformer	已有文档验证无误
28	torch.nn.TransformerEncoder	paddle.nn.TransformerEncoder	已有文档验证无误
29	torch.nn.TransformerEncoderLayer	paddle.nn.TransformerEncoderLayer	已有文档验证无误
30	torch.iinfo	paddle.iinfo		增加文档和单测
31	torch.finfo	paddle.finfo	增加文档和单测
32	torch.nn.CTCLoss	paddle.nn.CTCLoss	paddle, torch计算结果不一致，不确定是否设置功能缺失
33	torch.nn.functional.ctc_loss	paddle.nn.functional.ctc_loss	同 torch.nn.CTCLoss
34	torch.nn.PoissonNLLLoss	paddle.nn.PoissonNLLLoss		文档中eps参数名修改epsilon
35	torch.nn.GaussianNLLLoss	paddle.nn.GaussianNLLLoss		已有文档验证无误
36	torch.nn.MultiLabelMarginLoss			功能缺失，文档有误paddle.nn.MultiLabelSoftMarginLoss不能匹配
37	torch.nn.functional.multilabel_margin_loss	paddle.nn.functional.multi_label_soft_margin_loss	同 torch.nn.MultiLabelMarginLoss
38	torch.nn.SmoothL1Loss	paddle.nn.SmoothL1Loss	beta参数不为1.0时不支持，paddle.nn.SmoothL1Loss实际是对应torch.nn.HuberLoss
39	torch.nn.MultiLabelSoftMarginLoss	paddle.nn.MultiLabelSoftMarginLoss	已有文档验证无误
40	torch.nn.MultiMarginLoss	paddle.nn.MultiMarginLoss		已有文档验证无误
41	torch.nn.functional.triplet_margin_loss	paddle.nn.functional.triplet_margin_loss	已有文档验证无误
