[refactor] remove types_test (#8289)

* [refactor] remove types_test
1. remove types_test, it will cause core dump in higher version GCC or
   clang, because of memory align, some code will be vectorized in higher
   GCC or clang
2. Change string type length to 2 GB instead of -1
3. modify inaccessible code
