Persistent Storage: move example into a unit test

[rgoliver]

Problem

Reference: #4367

The KVS test is currently a self contained example application, this would be better as a unit test but currently EFR32 does not have a test runner.

Proposed Solution

Once all platforms with Persistent Storage have a test runner, move the example into a unit test.

@rgoliver I have implemented KeyValueStoreManagerImpl on nrfconnect and I need test added to the unit tests to verify if my implementation works well, as I don't plan adding persistent-storage example for nrfconnect. Are you ok with that I will copy example to the unit tests and after all platforms will have test runner, original example will be removed?

Sounds great, that definitely moves us in the right direction.

Moving to post V1.0, not clearly required for V1.0
