Description
修复paddle.incubate.softmax_mask_fuse_upper_triangle 遇到大tensor时报CUDA Error 9（非法配置）的问题。
问题出现的原因：
FusedSoftmaxMaskFuseUpperTriangleKernel和FusedSoftmaxMaskFuseUpperTriangleGradKernel中
Paddle/paddle/phi/kernels/fusion/gpu/fused_softmax_mask_upper_triangle_kernel.cu
Lines 191 to 193 in 4b03294
(attn_mul_batch + batches_per_block) / batches_per_block超过了GridDim.y的最大值，从而引起CUDA Error 9。修复方案
计算所需要的所有的block的数量然后采用一维划分的方法，然后在cuda kernel中每个block根据blockId以及原来划分方式的GridDim信息重新映射成原来的二维划分。
CUDA Kernel中引入了一次整数除法和整数取模的操作。
