Tej Singh fe3e762b6d Fix performance degradation from BootSequence atom
Adding the boot sequence reported atom in ag/3518079 caused the duration
of bootstat to increase, as seen in b/72864061. I isolated the cause
down to calling BootReasonStrToReason. However, this function also gets
called in ReportBootReason, so I created another function that does the
parsing and sets the system boot reason property, and made
RecordBootReason and statsd logging get that property.

Bug: 72864061
Test: rebooted phone, verified boot events were received in adb shell
logcat -b stats and verified adb shell bootstat -p printed correct
values. Ran timing tests as well on walleye with 20 boots: before this
change, the average was ~150-160ms. After, it was ~80ms.

# sys.logbootcomplete is a signal to enable the bootstat logging mechanism.

# during a runtime restart, which leads to false boot time metrics being reported.
#
# The 'on boot' event occurs once per hard boot (device power on), which
# switches the flag on. If the device performs a runtime restart, the flag is
# switched off and cannot be switched on until the device hard boots again.
