add target to build tests

[wfurt]

This will create zip files under artifacts/helix/tests - one file per each test set

I am thinking we can add another Linux task to build coreclr tests and libraries tests. And then a third FreeBSD task will extract those packs and run the tests.

That would make sense. I started with libraries as that generally covers coreclr as well.
But having PAL and coreclr tests may also help with other platforms. (as it would be example how to do it)

It seems like the build is timing out. Base build is 57m and that seems pretty slow.

[wfurt]

yes, I saw that and did the merge. test build is still running.

You can take a look at the output @am11. helix/runtime/test-runtime-netcoreapp5.0-FreeBSD-Release-x64.zip and all the helix/tests needs to be uploaded to FreeBSD. (maybe tar whole artifacts/helix) I'll figure out how to run the tests afterwards unless you want to give it trey as well. Each test zip file have runtest.sh and that needs to be executed with pointing at content of the test-runtime*.zip.

[wfurt]

correct for what? This should be test runtime aka HELLIX_CORRELATION_PAYLOD.
This + each test zip file should be sufficient to run test set.

I put find artifacts/helix to the build for that reason: https://cirrus-ci.com/task/5942372060102656

We generally need everything under helix. Each zip file under tests is individual test suite and they all point at same runtime from helix/runtime when executed. It may be easiest to just tar/zip whole artifacts/helix and unpack everything on FreeBSD host. From there we should be able to run the tests.
