DellEMC: Z9332F - Watchdog support, add platform.json, new platform API implementation and fixes (#6988)

Browse Source 
Incorporate the below changes in DellEMC Z9332F platform:

- Implemented watchdog platform API support
- Implement ‘get_position_in_parent’, ‘is_replaceable’ methods for all device types
- Change return type of SFP methods to match specification in sonic_platform_common/sfp_base.py
- Added platform.json file in device directory.
