[test] Adding platform.json configuration file unit test

[samaity]

Signed-off-by: Sangita Maity [email protected]

- What I did
In order to allow the SONiC community to check in platform capability file i.e. platform.json
file directly under device folder. We need to add this test to make sure the contents of the this file is compliant with platform capability design specified in DPB HLD doc

- How I did it
Added platformJson_checker.py file in Test folder.

- How to verify it

With the change as-is, build passes, the built image executed on the target platform, the configuration was applied properly.

Created a few bad platform.json files to test. Build got failed for all the bad platform capability file.
Build hit following failure:
