问题/功能描述
针对特定硬件平台（David）上使用N_BUFFER_33调度策略时，矩阵乘法分片算法性能不佳的问题进行优化。原算法直接使用硬件L0C缓存大小计算分片参数，在该特定场景下可能导致非最优的分片策略。本次修改旨在通过调整关键参数的计算逻辑，提升该场景下的计算性能。
修改方案描述
在GetParasCombo函数中，为核心参数mnMax的计算逻辑引入了调度类型相关的条件分支。对于非N_BUFFER_33的调度类型，沿用原有的L0C缓存大小进行计算。对于N_BUFFER_33调度类型，则使用一个经过优化的固定值（128KB）替代硬件L0C大小进行计算，从而为David平台上的该特定调度模式生成更高效的计算核函数参数组合。

描述
现象：a5场景下，部分case（在a3场景下执行正常）开启N_BUFFER_33特性，可能会出现tiling计算失败/aicore报错的问题
修改：针对a5环境下N_BUFFER_33特性使用场景，适配tiling计算逻辑

测试
对obp迁移用例（修改前部分用例会失败）进行批跑，结果正常无报错
