Description
paddle.Tensor.logit报错信息如下：
从报错中可以分析出在logit反向计算的结果与torch对不上。torch 反向结果一些值为NAN，paddle将其初始化为0。根据https://www.paddlepaddle.org.cn/documentation/docs/zh/3.0-beta/api/paddle/logit_cn.html#logit api的描述中发现，当参数eps被设置为None时>1 或者 < 0 的输入对应的输出被置为NAN。但是经过测试发现，在troch中这些输入的反向过程也置为了NAN而paddle将其置为0。这个问题不仅在big tensor中出现，尝试其他较小的shape时仍然也存在。
修复方法：
修改
logitGradkernel调用的LogitGradFunctor.operator方法，当eps没有被设置时，将其填充的值从0改为NANpaddle和torch的对比验证：
当eps参数被设置时：
当eps参数没被设置时（eps=None）：
前向和反向与torch都能对得上。
paddleAPITest中所有失败的config全部测试通过
#72973 中适用的修复方法与本PR修复方法基本一致，由于#72973 先合入develop分支，因此本PR用于完善单测
