Build Tribler by using GitHub Actions

[drew2a]

This PR adds the build.yml workflow for ubuntu that runs on each PR.

Also, it performs the first step of update_version_from_git.py refactoring: extracting update_version.py and update_metadata.py.

When I add a build workflow for each OS, update_version_from_git.py could be deleted.

This change is backwards-compatible with Jenkins one-click-release, but we must add the following lines to Jenkins before the call makedist_debian.sh:

          git describe | python -c 'import sys; print(next(sys.stdin).lstrip("v"))' > .TriblerVersion
          git rev-parse HEAD > .TriblerCommit

Nice improvements 👍

A concern is how it affects the Flatpak build and push to Flathub, that needs to be checked before merging.

          git describe | python -c 'import sys; print(next(sys.stdin).lstrip("v"))' > .TriblerVersion
          git rev-parse HEAD > .TriblerCommit

These commands are added to Ubuntu .deb builder on Jenkins

@xoriole I don't see any mentions of Flatpak in our repo.

Could you please give me a link to the Flatpak build?

Flatpak build is community contributed and is present here:
https://github.com/flathub/org.tribler.Tribler

Revisiting the config file, the Flatpak package is built using Debian package from the GitHub release URL. Therefore, this PR would not have any effect on that. So, my original concern regarding Flatpak build is invalid.
