[nrf noup] ci: NCS-specific CI tweaks

Necessary changes for NCS CI.

- Add a Jenkinsfile
- Add a commit-tags workflow: This enables sauce tag checking in sdk-zephyr
- compliance.yml: Disable check for merge commits, since we have upmerges
downstream. Also, since in the code we refer to Kconfig symbols that are defined
in the sdk-nrf repository, the Kconfig checks (Kconfig, KconfigBasic and
KconfigBasicNoModules) will not pass so exclude them. Also, disable any
maintainers-related checks
- scripts/gitlint: Extend the max commit line lengths for Gitlint to account
for sauce tags
- Adapt to the changes in:
nrfconnect/action-commit-tags#4
