Build/Test Tools: Various minor GitHub Action improvements.

This applies several types of improvements to GitHub Action workflows:
- Updates to inline documentation to ensure accuracy.
- Removal of repetitive or unnecessary debug logging.
- Reorganization of some steps to have configuration steps towards the beginning of jobs.
- Step name updates for consistency across workflows.

Props desrosj, jrf.
