[Mellanox] add ASIC temperature support to platform API (#4828)

Browse Source 
**- Why I did it**

System health feature requires to read ASIC temperature and threshold from platform API

**- How I did it**

Implement Chassis.get_asic_temperature and Chassis.get_asic_temperature_threshold by getting value from system fs.
