报错信息：
java.lang.IllegalArgumentException: The property of binding has been destroyed.
at com.dylanc.viewbinding.base.FragmentBindingDelegate.getBinding(FragmentBinding.kt:42)
重现步骤：
ViewPager+Fragment的场景，offscreenPageLimit=2，切换其他fragment再回到原来的fragment，原来的fragment的onFragmentHide方法里面使用binding做一些操作，然后就报错The property of binding has been destroyed.
看源码：override val binding: VB
get() = requireNotNull(_binding) { "The property of binding has been destroyed." }
判断_binding为空直接抛出异常的，能否开放提供一个方法判断_binding是否为空？这样再使用的时候判断是否为空，为空就不使用binding了
