Implemented unit test in build

[harmen-xb]

• Refactored github workflows to only workflow files (no actions) and include build, test and lint (including test report).
• Refactored all tsconfig files to re-use base config and all sub-folder tsconfigs to be composite.
• Fixed error in debug launch settings so debug-mode is set correctly.
• Upgraded jest dependencies to latest version.
• Refactored all jest configs to have local configs which re-use generic config.
• Performed yarn update
• Setup wokspace jest config which references to all projects.
• Updated gitpod config.
• Added VSCode Dev Container config.

As part of this PR for unit tests in the build I did some extra things which I want to check with you:

1. I first manually remove some packages from the package.json file in the root. After some other commits I realized that by doing this the yarn.lock is not updated. So I performed a 'yarn upgrade' to rebuild the yarn.lock based on the specified package versions. I do realize all dependencies are also updated if newer version are available wihin the version spec. Is this ok?
2. At some point I got errors on the moduleResolution setting. I then looked into the Theia repository and synched the settings with that repo in this commit: https://github.com/CrossBreezeNL/crossmodel/pull/30/commits/13585623ac9305a241109b930e49832fab813dcf. Does this have any dowside/side-effect I am not aware of?
3. I had issues with EsLint at some point which was due to an error in the include paths, which was fixed (https://github.com/CrossBreezeNL/crossmodel/pull/30/commits/0c42af9bb54620bb94ba50e92350be24cd1654ef). But before this fix I thought it was due to the tsconfig being wrong for the workspace or something. So I aligned it to be like the Theia or Theia Blueprint repo: https://github.com/CrossBreezeNL/crossmodel/commit/ab2a8fbb459ea2921e5154af4332a3867babd65e. Is this ok? Cause to me it looks better somehow, but again I don't know the side-effect of these changes.
4. I enabled executing 'yarn lint' in the workflow, but only for Ubuntu (since it's the fastest). I did this because if I understand it correctly, lint should have the same result in all OSes right? (https://github.com/CrossBreezeNL/crossmodel/commit/7b70a41b732f9219f3010ed2acfe1ef3b819cc97)
