20240726----Android6.0(RK3128)----修改低电时，低电通知改为低电弹框

客户觉得低电时，通知栏会通知低电，太low了
改好看点，就做了个低电弹框的UI

 packages/SystemUI/res/values/styles.xml
 packages/SystemUI/res/anim/batterylow_blink.xml                               
 packages/SystemUI/res/drawable/ic_lowbatterydialog.png                         
 packages/SystemUI/res/layout/battery_low_dialog.xml                            
 packages/SystemUI/src/com/android/systemui/power/PowerNotificationWarnings.java 

styles.xml 增加透明弹框效果
batterylow_blink.xml 是个动画效果，弹框将会闪三下进行低电警告
ic_lowbatterydialog.png 弹框图片，低电界面将会应用这张图片
battery_low_dialog.xml 低电界面
PowerNotificationWarnings.java 里边要注意的时 一般dialog都要"长"在activity上，不然的话要加上

dialog.getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY);

这样就可以了
