[ Impact ]

 * This is an update of thermald in noble to support Intel Core Ultra
Processors (Series 2), aka Lunar Lake and Arrow Lake

[ Test Plan ]

Pick each of the Alder Lake, Raptor Lake, Lunar Lake, and Arrow Lake
systems and run the following tests:

1. Run stress-ng, and observe the temperature/frequency/power with s-tui
  - Temperatures should stay just below trip values
  - Power/performance profiles should stay roughly the same between old thermald and new thermald (unless specifically expected eg: to fix premature/insufficient throttling)
2. check if thermald could read rules from /dev/acpi_thermal_rel and generate the xml file on /etc/thermald/ correctly.
  - this depends on if acpi_thermal_rel exist.
  - if the machine suppots acpi_thermal_rel, the "thermal-conf.xml.auto"
 could be landed in etc/thermald/.
  - if not, the user-defined xml could be created, then jump to (3).
  - run thermald with --loglevel=debug, and compare the log with xml.auto file. check if the configuration could be parsed correctly.
3. check if thermal-conf.xml and thermal-cpu-cdev-order.xml can be loaded correctly.
  - run thermald with --loglevel=debug, and compare the log with xml files.
  - if parsed correctly, the configurations from XML files would appear in the log.

[ Where problems could occur ]

 * The above test failed, which means the support for Lunar Lake and
Arrow Lake are incomplete, or regression happened on the supported
units.
