Build and run a test in CI (#10835)

* Actually build tests on Linux and allow RelWithDebInfo

They weren't being built.

Also cleaned up --config flags which enables RelWithDebInfo on Linux,
now that Ninja Multi-Config is used, it's quite trivial.

* Remove obsolete Slic3r Perl tests

The directory doesn't exist, they're already gone.

* Add GH job for running unit tests

* Move unit test execution to script and upload test results

* Don't run scheduled builds on forks

* Only deploy from SoftFever/OrcaSlicer

Will stop failures on forks

* Use artifact instead of cache

* Tweak archive and checkout paths

Keep getting error:

```
/home/runner/work/_temp/902d0a0a-6d23-4fe0-a643-8b5cc4efd25b.sh: line 1: scripts/run_unit_tests.sh: Permission denied
```

That seems to be because I didn't use actions/checkout, the working
directory is never setup correctly? So using checkout to get scripts
directory. Unsure if archive will preserve the `build/tests/` prefix;
will find out soon.

* Use tar to package directory and write results to correct directory

Tar preserves filenames and directory structure

* Use tar -xvf not -xzf

Muscle memory failed me

* Add testing wiki page

* Save test logs on failure and choose correct directory for junit

* Consolidate apt install steps, use for unit tests too, disable non-Linux builds

Temporarily disable non-Linux builds to save time while developing
this.

Cache the apt packages to save some time searching apt and downloading
them again (though I realize this is also downloading, but hopefully
by something closer and faster).

Remove all the redundant packages listed in the workflow and debian
distribution lists.

* Remove apt install steps from workflow

`./build-linux.sh -u` is supposed to install all needed packages, so
it should build without needing anything besides that. If I'm wrong
this commit will be dropped.

* Need composite action checked out locally

* Re-enable non-Linux builds now that it's working

* Skip a deploy and a notarize in forks

They only succeed in the main repo.

* Fix multi-build for non-Release builds: share CONFIG

* Correct build errors in unit tests

Indeterminate method signatures resolved. Updated script to build all
the tests.

* Fix -g vs -e for RelWithDebInfo

* Change CONFIG->BUILD_CONFIG

Missed one in prior commits

* Reduce wasteful redundant build artifact copies

1. Don't copy the artifacts and leave them; make a hard link first;
only make a copy only while creating AppImage.

2. Don't tar up the `package` directory; nothing uses this tar AFAICT

* Fix directory name

* Change jigsaw auth test URLs to httpbin.org

No idea why the basic auth doesn't work, but it doesn't work for
`curl` CLI either. This does.

* Remove force-build

It got reverted at
e3f049829b
for unknown reasons.

* Add timeout for unit tests in GitHub Actions workflow (#11146)
