Audit packages disabled in CI and enable all the ones we can

[LegNeato]

CI excludes packages here from building:

Without having these tested in CI, we will not be aware if they regress / stop building.

We should figure out why these are disabled and possibly create custom jobs for them if required.

The excludes were added in #1

With #188, I think we should be able to build add and even test it when we land #184.
The rest have to do with Optix, which we still don't have a solution for in our CI yet. I'm looking back to our discussion in #142. We'll need one if we want to remain its stewards.

The OptiX ones I think the major issue is OptiX SDK installation which users will have to accept a licence and there is no public download URL without login.

Seems then the best anyone ever could do is build and test locally. Then these would just stay disable indefinitely.
