Feature/update internal workflows

[n0900]

Remove copy/paste redundancy and maintenance nightmare in github actions via reusable actions.
Actions are now configured using strategy matrices in json format

Depends on a-sit-plus/internal-workflows@modularTests / WIP

[n0900]

In this repo build was not rolled into build-everything as in vck and signum because the steps are substantially different.

(Copied from Signum PR)
common-setup also manages caches effectively using the official setup-gradle action which can be configured. Current setup is it updates the cache automatically iff action is performed on main or development and Test Everything is triggered on push to either. Caches are never deleted - github purges the unused automatically when hitting the limit.

Caching would look like this

In the cloned repository the windows runner fails the reporting step but this cannot be reproduced in the main repository.

Also notice the nice cache reporting in

So the pipeline is failing? Is the shared module now built twice, once when building the app, and once when running the iOS tests?

Pipeline was not failing - this was a fastlane issue.
As it was before the modules were built twice. I've now redesigned the original files to use the new common actions but left the rest the same.
