* Shellcheck all shell scripts
* Implement Shellcheck's recommendations
* Shellcheck the distribution-specific files
* Include the distro scripts to trigger action
* Fix array usage (hopefully)
* Use single-quote string
TIL: single quote string in yaml treats everything as literal, but
double quote allows backslash escaping.
* Make all cmake commands use set+-x dance and fix macos getopts line
Make Claude happy
getopts has colon after a command which takes an argument

* Shellcheck on build_linux.sh and tiny refactor
`shellcheck -e SC1090 build_linux.sh` and fixed the issues.
Also fixed the usage command to return an error, simplify directory
creation to use `mkdir -p`, and made printing of the cmake commands
consistent instead of having three different ways of doing it.
* Reorder functions in more pleasing way
* Add shellcheck to workflows
This is the beginning of adding some safety nets for making
changes. Currently it just runs shellcheck against `build_linux.sh`.
You can see it working at
https://github.com/coryrc/OrcaSlicer/actions/workflows/shellcheck.yml
I forked and tested it running in PRs and against pushes to HEAD.
* Rerun shellcheck
