v0.4.0

Release notes

Added

• CodeChecker workflow. On every push to the main branch it builds the
  firmware, analyses it and stores the analysis to the CodeChecker server.
  In PRs it builds, analyses the state of the feature branch and compares it
  against the last server analysis.

Changed

• Improve existing build.yaml and twister.yaml workflows.
  • APT dependencies are now installed directly in the workflows instead
    of in the makefiles. They can now be cached, which means faster setup
    time of required workflow environments.
  • make install-test-dep target was completely removed due to the above
    change.
  • Build workflow is now triggered on every push to the main branch.
    Only new make quick-build target is run in that case, everything
    else stays the same.
  • make build was renamed to the make release to better convey its
    purpose.
• Documentation in workflow-templates/zephyr/README.md was updated
  accordingly.

Fixed

• Fixed incorrect caching of nrfutil-toolchain-manager.exe.
