[feature] OneFlow和PyTorch兼容性测试

[BBuf]

oneflow ci里面的兼容性测试框架：

Oneflow-Inc/oneflow#6076

原理就是把pytorch实现的模型，直接import oneflow as torch run一次看是否存在bug以及Loss的差距是否比较大来测试兼容性。

本次任务需要完成flowvision所有的模型的兼容性测试，并且把所有不兼容的接口记录下来在0.8.0之前解决。

最后需要提供2个表格，分别是算子兼容性和模型兼容性，表格还需要调研一下写成什么样子。

后续会提供兼容测试的分工。

关于oneflow.nn.functional.conv2d的bug

>>> flow.__version__
'0.7.0.dev20220224+cu112'
>>> torch.__version__
'1.10.2+cu102'

---

一些参数需要显式指定才行，而且会报TypeError: conv2d(): missing required argument channel_pos的bug，复现如下：

>>> from oneflow.nn.functional import conv2d
>>> img = flow.ones(1,3,224,224)
>>> kernel = flow.randn(3,1,3,3)
>>> conv2d(img, kernel, groups=3)
