[SMOKECO] - Follow up: Update Highest priority alarm PIXIT to dynamic values in the code.

[jtrejoespinoza-grid]

This is a follow up for: project-chip/connectedhomeip#43712

Summary Title:

Update PIXIT values from the HIEST_PRI_ALARM.

Description:

Currently the PIXIT values for HIEST_PRI_ALARM look as they are custom and should be provided as part of the certification but its not 100% clear and how is implemented from the test plan it encourages the testers to play with the values until get a valid set of values for the HIEST_PRI_ALARM which can be harmful.

Alternative from this scenario we think the following can be done to solve this issue:

In step 22 (1st HIEST_PRI_ALARM):

ensure ExpressedState is one of [BatterAlert, InterconnectSmokeAlarm (if available), InterconnectCOAlarm (if available), COState, SmokeState]
save value as last_highest_alarm
In step 25:

if last_highest_alarm was not COState, ensure ExpressedState is last_highest_alarm
else ensure ExpressedState is one of [BatterAlert, InterconnectSmokeAlarm (if available), InterconnectCOAlarm (if available), SmokeState]
save as last_highest_alarm
In step 28:

if last_highest_alarm was not InteronnectCOAlarm, ensure ExpressedState is last_highest_alarm
else ensure ExpressedState is one of [BatterAlert, InterconnectSmokeAlarm (if available), SmokeState]
save as last_highest_alarm
