[nrf noup] ci: NCS-specific CI tweaks

squash! [nrf noup] ci: NCS-specific CI tweaks

- Add a Jenkinsfile
- 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.
- Extend the max commit line lengths for Gitlint to account for sauce
  tags
- Add a commit-tags workflow: This enables sauce tag checking in sdk-zephyr
