Describe
Task: PaddlePaddle/Paddle#35966
Add pytest of paddle.nn.Upsample. Because there are too many lines of code , so I split the code into two files.
The two files share the same "class TestUpsample(APIBase):"

[kolinwei]

这两个文件现在是怎么区分的？合成一个测试文件吧

如果合并成一个文件，因为代码行数过多，有1423行，在本地git commit 时有如上失败信息，而且无法进行git push。即使通过upload file 方法把合并的文件上传成功后，checks中的CodeStyle会报如下错误：

paddle.nn.Upsample 支持 5种resample methods， 由参数mode指定:
'linear' : Linear interpolation
'bilinear' : Bilinear interpolation
'trilinear' : Trilinear interpolation
'nearest' : Nearest neighbor interpolation
'bicubic' : Bicubic interpolation

test_upsample_part1.py 测试 mode 为 'linear', 'bilinear' 的情况，
test_upsample_part2.py 测试 其他 3种情况

用例最好放在一个文件里面，可以把定义的一些函数或者类放到一个单独文件里，比如upsample_utils.py
