Describe

主要修改点：

  1. 初步添加对sympy表达式的支持（设计方案：sympy_to_func）
  2. 添加在 LinearElasticity 和 NavierStokes 上的单测，测试结果如下
>>> pytest test/utils/test_linear_elasticity_sympy.py

test/utils/test_linear_elasticity_sympy.py ........                                                                                                                                                                                                        [100%]
Results (12.47s):
         8 passed

>>> pytest test/utils/test_navier_stokes_sympy.py

test/utils/test_navier_stokes_sympy.py ....                                                                                                                                                                                                                [100%]
Results (17.04s):
         4 passed

其他：

  1. 修复 LinearElasticity 内，未正确处理dim=2而可能导致KeyError的情况；删除无用的 navier_x/y/z 系列表达式，并修改相关单测
