This refactor includes the following changes: - Refactor similar tests using `types::for_each` to remove redundant code; - Explicitly include the missing header `type_algorithms.h` in some test files; - Some tests scattered in different test functions with ad-hoc names (e.g., `test5()`, `test6()`) but belong to the same kind are now grouped into one function (`test_struct_array()`).
