Currently HwASan has no fiber switch interface for coroutines. This PR adds fiber switch interfaces similar to ASan which helps to pass sp check correctly on unwinding. The only difference is HwASan does not need a fake stack since tags can do the same thing (e.g., detect UAR). Interfaces are made identical with ASan's. Also adds unit test which is similar to ASan with minor adjustments: 1. change `__asan_handle_no_return` to `__hwasan_handle_vfork` 2. remove huge stack test since `__hwasan_handle_vfork` has no stack size limitation. 3. use uninstrumented globals to simulate allocation since hwasan do not support tagged pointer while using `longjmp` The testcase is tested on both x86 with alias mode enabled and aarch64.
