-// TilingKey 的生成规则：
-// FlashAttentionScore/FlashAttentionScoreGrad 十进制位组装tiling key，包含以下关键参数，从低位到高位依次是：Ub0, Ub1,
-// Block, DataType, Format, Sparse, 特化模板 Ub0、Ub1:
-//     表示Ub核内切分的轴，使用枚举AxisEnum表示，因为我们允许最多切分两根轴，所以存在UB0和UB1，如果没有UB核内切分，
-//     那么填AXIS_NONE。UB0和UB1各占一个十进制位;
-//     Block: 表示UB用来分核的轴，使用枚举AxisEnum表示，占一个十进制位;
-//     DataType: 表示当前tiling key支持的输入输出的数据类型，使用枚举SupportedDtype来表示，占一个十进制位
-//     Format: 表示当前tiling key支持的Format, 使用枚举InputLayout表示，占一个十进制位
-//     Sparse: 表示当前tiling key是否支持Sparse，使用枚举SparseCapability表示，占一个十进制位
-//     其余特化场景，定义自己的位域和值
