[Packaging] Publish AdaptiveCpp package for Ubuntu

[normallytangent]

This PR adds a Github workflow for publishing AdaptiveCpp packages on every git-push.

• Currently the debian directory is handled manually: ideally I would want to automate this
• Publish the resulting artifact on Github
• Package for architecture any
• Use custom compiler
• Separate packages for cpu/sscp and cpu/cuda/rocm/ze backends

I tried adding a job for a rocm backend, but it runs out of storage space when installing the rocm ubuntu package.
In theory, it should work with a runner that has more storage.

Here it is, in case it helps -

@DhruvDh Thanks. I think the space problem can be solved by thinning out the default runner image a little, as we already do here:

AdaptiveCpp/.github/workflows/linux.yml

Line 145 in b9b9d32

- name: Free Disk Space (Ubuntu)

However, I don't think that we need a separate ROCm package. We can just have one that supports everything :) Then what it can offload to only depends on whether users have CUDA/ROCm/OpenCL etc installed. I think the lack of ROCm support in the current version of this PR is just due to it being WIP.
(and probably we shouldn't target ROCm 6.0, as it has some issues)

[illuhad]

Do I understand correctly that the packages are now ready for testing? If so, I call on everybody reading here to give them a try and see if they work :)

[normallytangent]

The packages at this stage in this branch are ready. Would be great to hear some feedback, especially if the configuration even works.
I am currently working on a way to introduce a testing-friendly naming convention for the binaries. Which is on a separate branch on my fork for reasons that I keep needing to make multiple commits with tiny changes to make the CI happy.
