Subject: [PATCH 2/3] docker: Support docker for CI or dx

Just run the native helper script in docker,
it is not optimized for bandwidth but minimize duplication of changes.

Subject: [PATCH 3/3] github: Add action for checking PR in developers forks

Enable github actions that build any branches using docker along helper script.
To reduces the dependency on github and
avoid bringing more ambiguity or complexity
most tasks are isolated at lowerlevel (in helper for cmake).

More checks to come next, unit tests, lint etc.
