[nrf noup] ci: NCS-specific CI tweaks

Necessary changes for NCS CI.

- Add a Jenkinsfile
- compliance.yml: Disable check for merge commits, since we have upmerges
  downstream.
  Add an additional check for sauce tags (details in scripts/gitlint)
  Also, since in the code we refer to Kconfig symbols that are defined
  in the sdk-nrf repository, the Kconfig checks (Kconfig and
  KconfigBasic) 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
- scripts/gitlint: Add support for sauce tags checks. In order to not
  interfere with CI in other repos (namely sdk-nrf) this is run as an
  independent gitlint invocation and not as part of check_compliance.py.
  This invocation enables the ncs-sauce-tags rule and, since it runs
  before rebasing and thus will run on merge commits, disables the
  title-starts-with-subsystem rule by setting a catch-all regex.
