RK3576 Android14 状态栏和导航栏增加显示控制功能

问题背景：

因为RK3576 Android14用户需要手动控制状态栏和导航栏显示隐藏控制，包括对锁屏后下拉状态栏的屏蔽，在设置功能里增加此功能的控制，故参考一些博客完成此功能，以下是具体代码路径的修改内容。

解决方案：

1、修改系统默认配置

代码位置：device/rockchip/rk3576/device.mk

PRODUCT_PROPERTY_OVERRIDES += \
+    persist.sys.statusbar.enable=true \
+    persist.sys.navigationbar.enable=true

2、修改SystemUI

android/frameworks/base/packages/SystemUI/AndroidManifest.xml

    <protected-broadcast android:name="com.android.systemui.action.ACTION_LAUNCH_MEDIA_OUTPUT_BROADCAST_DIALOG" />

+    <!-- For statusbar show or not -->
+    <protected-broadcast android:name="com.systemui.statusbar.show" />
+    <protected-broadcast android:name="com.systemui.statusbar.hide" />
+    <!-- For NavigationBar show or not -->
+    <protected-broadcast android:name="com.systemui.navigationbar.show" />
+    <protected-broadcast android:name="com.systemui.navigationbar.hide" />
