[Paddle] 0维Tensor推全

[qili93]

主框架相关背景和计划见：https://ku.baidu-int.com/knowledge/HFVrC7hq1Q/yKeL8Lljko/6UmOO2EkH2/Gv4bMvQxAw61WT

当前状态：

• 目前主repo的输入0D已经完成，输出0D完成50%，剩余正在升级中，见 任务明细表 - 输出0D，预计会在4月合入
• PaddleCustomDevice在主框架完成对所有0维Tensor的修改之后，需要参考主框架修改相应升级Kernel代码对0维Tensor的支持，并增加对0维Tensor的单测case

开发计划：

• 主框架4月底之前会完成所有0D的修改，到时候主框架提供修改后的PR List给到PaddleCustomDevice进行修改

主框架这边已全部完成输出0D。PaddleCustomDevice之前已完成了输入0D，未开展输出0D，需要对输出0D进行支持。
由于输出0D改动kernel较少，大部分改动集中在infermeta，预计PaddleCustomDevice的kernel改动不会很多，具体改动可以在将test_zero_dim_tensor中的动态图case拷贝到PaddleCustomDevice中，如能通过即可。

主框架这边输出0D的PR List有：

• [Zero-Dim] Support broadcast_tensors input 0D and distribution API output 0D Paddle#51721
• [Zero-Dim] Support output 0D for argmin/argmax/median/kthvalue/mode/equal_all/allclose, test=allcase Paddle#51889
• [Zero-Dim] Support paddle.all/any/min/prod/logsumexp/amax/amin/quantile/some loss output 0D, test=allcase Paddle#53051
• [Zero-Dim] Support paddle.max output 0D, test=allcase Paddle#53242
• [Zero-Dim] Support paddle.sum/mean/loss api output 0D, test=allcase Paddle#52739
