优化 compute_rhs_bssn 热点路径并加入 NaN 检查开关

Browse Source 
- 用 DEBUG_NAN_CHECK 宏按需启用 NaN 检查，并在输入/宏生成器中新增 Debug_NaN_Check 配置
  - 逆度量改为先求行列式再乘法展开，减少除法；并在 Gam^i/Christoffel 处提取公共子表达式
  - 预置批量 fderivs 辅助例程，便于后续矢量化/合并导数计算
  - 将默认 MPI_processes 调整为 8

  变更涉及：

  - AMSS_NCKU_source/bssn_rhs.f90
  - generate_macrodef.py
  - AMSS_NCKU_Input.py
  - AMSS_NCKU_Input_Mini.py
  - inputfile_example/AMSS_NCKU_Input.py
  - AMSS_NCKU_source/diff_new.f90
