Enhance unit test to check for reset of values on initialization (requirements related)

[skliper]

Is your feature request related to a problem? Please describe.
It's difficult functionally (or via CTF) to confirm the reset requirements related to counters/states since they get populated/used and counters increment based on the configuration.

Requirements that would help to check in coverage tests:
cSB4500 - SB: Initialize Routing On Power On Reset | Upon a Power-on Reset the cFE shall initialize the Routing Information and clear all error counters.
cSB4501 - SB: Initialize Routing On Processor Reset | Upon a Processor Reset the cFE shall initialize the Routing Information and clear all error counters
cTIME2002 - TIME: Zero Counters | Upon receipt of Command the cFE shall set to zero all counters reported in Time Services telemetry.

Describe the solution you'd like
Add a quick assert that the values do get initialized (typically in CFE_*_EarlyInit) as required.

Describe alternatives you've considered
None

Additional context
None
