SnapdragonCamera: Switch to SD card when internal storage is full

When internal storage is full, switch to SD card for storage.
Change the save path from internal storage to SD card when
updateStorageSpace is called if:
1. Internal storage is the current save path and does not have
   enough space
2. SD card has enough space

Display a toast message and update display of the save path menu
item when the storage path is switched.
