[DellEMC] S5212F and S5224F 2.0 API changes (#10315)
Why I did it
S5212F - Platform API 2.0 changes
S5224F - Platform API 2.0 changes
How I did it
Implemented the functional API's needed for Platform API 2.0
Added media_settings.json, pcie.yaml, platform.json, system_health_monitoring_config.json files.
How to verify it
Used the API 2.0 test suite to validate the test cases.
