[Xiangyu-Hu]

This pull request introduces several updates across the codebase, focusing on dependency management, type handling improvements, logging functionality, and mesh dynamics refactoring. The most significant changes include adding support for spdlog for logging, refining type handling with std::string_view for improved type name extraction, removing unused code related to mesh dynamics, and restructuring mesh-related files.

Dependency Management:

• .github/workflows/ci.yml: Added spdlog as a dependency in multiple sections of the CI configuration. [1] [2] [3] [4] [5] [6] [7]
• CMakeLists.txt: Integrated spdlog into the build system and linked it to sphinxsys_core.

Type Handling Improvements:

• src/shared/common/ownership.h: Added a type_name utility function using std::string_view for extracting type names in a compiler-independent manner. Updated dynamic casting error messages to use type_name instead of typeid. [1] [2] [3]
• src/for_2D_build/common/data_type.h and src/for_3D_build/common/data_type.h: Standardized template parameter naming conventions for consistency (ArraySize instead of array_size). [1] [2]

Logging Functionality:

• src/shared/io_system/io_log.cpp and src/shared/io_system/io_log.h: Introduced a logging system using spdlog. Added initialization and retrieval functions for the logger. [1] [2]
• src/shared/io_system/io_environment.h: Added methods to retrieve folder paths (inputFolder, outputFolder, restartFolder, reloadFolder) for use in logging.

Mesh Dynamics Refactoring:

• src/shared/mesh_dynamics/mesh_dynamics.h: Removed unused parallel execution policies and iterators for mesh cells. Simplified mesh dynamics classes by replacing custom parallel iteration logic with mesh_for. [1] [2] [3] [4] [5] [6] [7]
• Renamed file src/shared/meshes/mesh_dynamics.h to src/shared/mesh_dynamics/mesh_dynamics.h for better organization.

Code Cleanup:

• src/shared/meshes/base_mesh.h: Removed unused includes and code related to memory pooling and containers.
• src/shared/common/sphinxsys_containers.h and src/shared/common/sphinxsys_variable.h: Removed unused typedefs and template definitions for mesh variables. [1] [2]
• src/shared/io_system/io_all.h: Added io_log.h to the list of includes.
