Moonshot: Add Android Termux support

[Slackadays]

It turns out that there is no single easy way to compile Android apps in Termux in GHA*. However, it's possible to have an Android VM and a Termux SSH session. This should fit well into CPA if it's possible to have such a setup. Having the ability to have an Android action would let me have nightly builds for Clipboard to verify Android compatibility.

*excluding the possibility of a self hosted runner on some Android box
Edit: Looks like GHA requires .net Core, so self hosted on Termux is currently out until termux/termux-packages#516 is satisfied. One alternative would be to have a regular GH Action SSH into the runner server and run the command there, so maybe that would be more viable for you to implement here?

Double edit: Self hosted has nothing to do with CPA

I just realized that there's another potential CPA to add here. It would be a "generic" action that runs on either the standard GHA runners or a self-hosted one. However, whatever you tell this generic action to do will execute on a different system that's accessed through SSH. That way you could theoretically have CPA for any system as long as it supports SSH.

Let me see if I understand this correctly. There should be a VM running Android. In that VM Termux should be installed and running. Any commands specified in the action should be executed inside Termux. Is that correct?

Hmm, I think this is out of scope of CPA. Even though CPA uses SSH to communicate with the VM I consider this an implementation detail. To me it sounds like one would need a completely different API for the action.

Perhaps this is better discussed in the Discussions section.
