  Log Message:
  -----------
  [Clang][Interp] `__builtin_os_log_format_buffer_size` should be an unevaluated builtin (#99895)

Follow the current behavior of constant evaluator,
`__builtin_os_log_format_buffer_size` should be an unevaluated builtin.

The following code is well-formed:
```
void test_builtin_os_log(void *buf, int i, const char *data) {
  constexpr int len = __builtin_os_log_format_buffer_size("%d %{public}s %{private}.16P", i, data, data);
}
```
