thermal: intel: int340x: Support MSI interrupt for Lunar Lake

The legacy PCI interrupt is no longer supported for processor thermal
device on Lunar Lake. The support is via MSI.

Add feature PROC_THERMAL_FEATURE_MSI_SUPPORT to support MSI feature per
generation. Define this feature for Lunar Lake processors.

There are 4 MSI sources:
 0 - Package thermal
 1 - DDR Thermal
 2 - Power floor interrupt
 3 - Workload type hint

On interrupt, check the source and call the corresponding handler.

Here don't need to call proc_thermal_check_wt_intr() and
proc_thermal_check_power_floor_intr() to check if the interrupt is for
those sources as there is a dedicated MSI interrupt.
