[nrf fromtree] [HVAC] Implement TC-TSTAT-2.2 (#36023) (#37515)

* Initial generated test

* Fixed and compared against test plan

* Remove unused TC-TSTAT-2.2 yaml

* Apply suggestions from code review

* Update TC_TSTAT_2_2.py

fixed below mentioned discrepancies on the code:

Step-3c: The test plan expects a Success response, but the script is checking for a ConstraintError. If the value does not violate any conditions, the response should be Success. In such cases, the test will fail.
Step-4c: If the AUTO feature is enabled, the script writes the UnoccupiedCoolingSetpoint attribute with MaxCoolSetpointLimitValue and checks for a ConstraintError response, which is not required.
Step-5c: The script should check the following condition when the AUTO feature is enabled: Min(MaxHeatSetpointLimit, (UnoccupiedCoolingSetpoint - MinSetpointDeadBand)). However, this condition is missing in the script, and it incorrectly checks for a ConstraintError response.
Step-7a: The write and read verification is missing.
Step-9b: The script incorrectly writes the attribute value using AbsMinCoolSetpointLimitValue instead of MinCoolSetpointLimitValue.
Step-9c: A duplicate read check has been removed.

* Python linter fix for TC_TSTAT_2_2

* Update src/python_testing/TC_TSTAT_2_2.py

* Restore setpoints to original values at end of test

* Use get_endpoint method to find active endpoint

* Update CI Test Arguments to the apparent new style
