Use /persist as Qualcomm time fix source during early boot

Browse Source 
* /persist can be mounted early while TWRP is parsing the fstab so
  as soon as the partition is parsed, mount and adjust the time
  accordingly.

* Store a backup settings file on /persist. Having a 2nd copy of
  the settings file in the /persist partition allows for early
  reading of the file and adjust timezone and brightness to user
  preference while still on TWRP splash.

* Add the qcom ats time offset in TWRP settings file and use it
  if no better ats file is found. This will also allow devices
  with a persist partition, but no ats files in it, to adjust
  the time offset during early boot.

* Use /persist/time/ as Qualcomm time fix source, based on
