RK Android 8.1强制第三方APK横屏

修改：

frameworks\base\services\core\java\com\android\server\policy\PhoneWindowManager.java

@Override
public int rotationForOrientationLw(int orientation, int lastRotation) {
    if (false) {
        Slog.v(TAG, "rotationForOrientationLw(orient="

将 mForceDefaultOrientation 改为 true，默认返回 Surface.ROTATION_0 横屏
