Use /persist as Qualcomm time fix source during early boot
* /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
