Fix #1483, Add CI workflow to run cFE coverage tests

[pepepr08]

Describe the contribution
Fix #1483
Run cFE coverage tests for every push and pull request. Use a checks-for-duplicates job to avoid duplicate runs of the CI Action.

Testing performed
Steps taken to test the contribution:

1. Pushed to fork, CI action ran successfully: https://github.com/pepepr08/cFE/actions/runs/886331016
2. Created a temporary branch and introduced an ES bug to force a workflow failure. Workflow failed successfully: https://github.com/pepepr08/cFE/actions/runs/886371053
3. Reverted commit that introduced bug to verify that workflow run completed successfully.

Expected behavior changes
A new workflow is added when looking at the different nasa/cFE actions. The workflow will run for every push and pull request.

System(s) tested on

• Tested on the Github servers where CI actions get to run.
