Closes #2166

Add a workflow to verify all patches to OpenWrt and the packages feeds
are refreshed. If they are not, the workflow fails.

The performance benefit the cache brought was due to a broken sources
CDN mirror handling in OpenWrt.

The cache brings no measurable performance benefit. Disable it to slim
down the pipeline steps.

This adds the ability to cache OpenWrt dependencies on a per-target
base. Artifacts over 10MB are excluded, as GitHub imposes a limit of 5G
of available space per repository cache. This affects mostly
linux(-firmware) and gcc / gdb.

The goal is to reduce the total amount of requests necessary to fetch
dependencies.

This adds a new workflow for building the Gluon documentation.

In contrast to the existing build workflow, the documentation
is built for every branch, as it only takes around two minutes
to render the HTML documentation.

- Rely on shebang instead of setting shell in workflow
- Run whole install-dependencies.sh in sudo
- Use /bin/sh instead of bash
- set -e

The new step is added with `if: ${{ !cancelled() }}`, so the logs are
stored even when the build fails.

This enables build-testing only on master as well as next and release
branches.
