Test Linux Binaries after they're built in CI (Cont'd) (#162)

* Add jobs to test multi-arch binaries to build.yml workflow after the build-linux job. 
* Remove the separate workflows initially created to test the binaries, which got triggered by workflow_run but only ran in the default branch. This was extremely difficult to manage, and the testing of the binaries didn't add much processing time to the existing build.yml workflow.
* The two (2) new binary testing jobs now send two (2) new "release candidate" builds to Coveralls.io for each newly built `x86_64` and `aarch64` binary. 
* The binaries are tested not only against the new coverage report from the current CI run of coverage-reporter, but also against all the coverage reports in different formats included in the test fixtures of coverage-reporter's code base, which provides verification that the new binaries can process all known formats.
* Use dawidd6/action-download-artifact@v3 action instead of actions/download-artifact@v4 to share artifacts across workflows. (actions/download-artifact@v4 officially supports this now, but we couldn't get it to work.)
