ci: Add Coldcard simulator

[jirijakes]

An attempt to add Coldcard simulator.

Notes:

• Pulls ~10 GB of source code. Unfortunately, adding --shallow-submodules was failing on one of the repositories.
• Whole docker image is ~14 GB.
• New docker build takes ~20 minutes, most of it is git clone.
• Pulls 6.2.2X, I did not manage to build 5.2.2 successfully.
• So far did not touch tests, some are failing.

I don't know how to continue and I don't know exactly what is the problem. Is the image too big (14G)? I thought for public repositories, the limit was more than that.

I assume it's the image size but at this point, I don't know how to reduce it.
