Add match threshold alarm signals for threshold events

Add SEL_LOGGER_MONITOR_THRESHOLD_ALARM_EVENTS option to enable
monitoring the alarm signals on sensor threshold interfaces:
https://gerrit.openbmc-project.xyz/39899

Tested:
Change the threshold to trigger the alarm signal:
busctl set-property xyz.openbmc_project.Hwmon-487368426.Hwmon1
/xyz/openbmc_project/sensors/temperature/cputemp
xyz.openbmc_project.Sensor.Threshold.Critical CriticalHigh d 30

trigger the event log:
1 |  Pre-Init  |0000000213| Temperature cputemp
| Upper Critical going high | Asserted
| Reading 35 > Threshold 30 degrees C

Note:
It needs to work with the following PR:
