Use __CET__ macro to enable IBT support. (#11081)

According to the GCC documentation [1], the macro `__CET__` is dfined when `-fcf-protection` compiler option is used. Therefore use this macro to enable IBT support instead of special casing for `__OpenBSD__`. [1]: https://gcc.gnu.org/onlinedocs/gcc/Instrumentation-Options.html#index-fcf-protection
