[Mellanox] Refactor Mellanox platform API to support dynamic port configuration (#8422)
- Why I did it
* To support systems with dynamic port configuration
* Apply lazy initialization to faster the speed of loading platform API

- How I did it
* Add module.py to implement dynamic port configuration (aka line card model)
* Adjust chassis.py, platform.py, thermal.py, sfp.py to support dynamic port configuration
* Optimize existing code

- How to verify it
Platform regression on MSN4700, MSN3800 and MSN2700, 100% pass
Unit test covers all new changes.
