- consolidate configuration
- DRY improvements
- improve flexibility/robustness in the face of missing reference test info
- add reference test info IDs and additional logging to help diagnose testing failures
- includes parallel refactor of 'util/run-gnu-test.sh'
- the build and test steps won't run until/unless Dependency and MSRV checks pass
- code coverage won't run until/unless the build steps all pass
## [why]
This helps make more efficient use of CI resources and can help more easily visualize
build issues from the resultant GHA dashboard flow diagram.
## [why]
`cspell` in CI started mysteriously failing mid-2021. Tracking down the
error took some time as it was not obvious from `cspell` feedback where
the issue lay. Ultimately, it was discovered that `cspell` had deprecated
use on NodeJS versions < v12 for `cspell` v5+.
`cspell` is now pinned to v4.2.8, with a maintenance note to allow an
upgrade to the `cspell` version when a version of NodeJS >= v12 is being
used in the CI.
An issue requesting better tool feedback for similar situations was also
opened on the `cspell` repo.[*]

# [why]
The tool cache is currently failing and seems to be getting further behind current
versions. The [actions-rs/install#12] issue addresses this but seems to be
languishing without any proposed solution.

- fixes conversion of new `cargo clippy` output style to GHA annotations
## [why]
`cargo clippy` output formatting changed, using relative instead of absolute paths.
