s2: add qcamerasvr restart workaround

Unfortunately, s2's mm-qcamera-daemon has an issue where sometimes it can't receive any valid preview frame at times which causes the camera to black screen and fail to work until a reboot is performed. This issue could be due to us using camera HAL3 when LeEco only inteded for HAL1 to be used as HAL3 is disabled on our stock ROM.

Without the source code to mm-qcamera-daemon and the camera blobs we cannot currently fix this issue. A workaround we can do though to prevent a reboot is to restart the qcamerasvr manually by adding a setting for it.

Another workaround is to use camera HAL1 as it works perfectly, especially in certain apps like WhatsApp where switching between front/rear camera repeatedly causes the blackscreen issue in camera HAL3.

This commit is co-authored by @zhaoguomanong as he implemented a better camera reset implementation, added a camera HAL3/HAL1 toggle and also created shortcuts in the app drawer for s2 users to be able to use quickly instead of having to always go into Settings > Advanced > LeEco Settings.
