rk3562 android 14 延长开机动画规避fallbackhome黑屏

Android 的设备无论哪个版本从开机到快进入桌面时候都会有一个加载过程，如果是没有锁屏的像一些box产品或者用Android做的非手机平板的设备为了体验更好一点，都会去掉中间的加载过程，其实就是原生设置的fallbackhome,如果是第一次开机还有一个引导的界面的过程，这个rom直接去掉该apk就好，但是引导完成的属性要在其他地方补充上，不然会出现可能会开发者模式打不开或者usb调试开不了。这里主要是举例如何去掉fallbackhome。以下是Android14 的修改：

最后在framework的监听acitivty页面启动地方添加要识别的包名：
