不建议在kernel中重新进行shape推导和Resize操作。如果可以请修改到infermeta中以及同步修改到符号推导中。

原kernel是在结尾做的Resize，如果修改到infermeta，需要kernel都修改，改动较多

和paddle/phi/kernels/gpu/slogdeterminant_kernel.cu中的修改同理。

Description
[0-size Tensor No.106、115] Add 0-size Tensor support for slogdet/det
paddle.linalg.slogdet
slogdet前向返回维度是输入去掉结尾两个维度，然后在开头增加一个2，比如输入是[*, M, M] ，返回是[2, *]，所以是判断*中是否包含0，并且输入的结尾两个维度需要相同，paddle和torch都有检查
反向是Alloc后return
前向GPU单独文件，其他在impl实现
infermeta没有修改
增加单测
PaddleAPITest测试，已修复cuda error问题，结尾两个维度需要相同，如果不同paddle和torch都有错误
paddle.linalg.det
前向和反向维度已设置，判断numel后Alloc返回
前向GPU单独文件，其他在impl实现
infermeta没有修改
增加单测
PaddleAPITest测试，已修复cuda error问题，结尾两个维度需要相同，如果不同paddle和torch都有错误
