Add yang model for PFC watchdog debug information (#16206)

Browse Source 
### Why I did it
When PFC WD is triggered there is no diagnosis information which makes it difficult to understand why PFC WD was triggered. So, we add a field `additional_information` to accommodate the diagnosis information.

### How to verify it
unit test
