Assorted cleanup of CI/packaging related code. (#16938)

* Drop unused Dockerfile.test.

It’s not been used for years, and it doesn’t even work at this point for
it’s intended purpose.

* Remove CodeClimate configuration.

We’re not using it anymore, so there is no point to keeping the
configuration around.

* Remove the build_external directory.

This isn’t used by any of our code AFAICT, and if it _is_ needed, it
should actually be in some sub-directory of `tests` instead of a
top-level directory whose name doesn’t even describe what it does.

* Remove .gitattributes

If there's any objection we can reinstate it.

* Move coverity-scan.sh under packaging/utils

* Move cmake files under packaging/cmake

* Remove devcontainer

* Fix up coverity script to run correctly from new location.
