[ci][docs] Simplify the doxygen job.

- Remove the override step from the doxygen job.  Overrides can be
  specified as command-line arguments, which significantly shortens the
  job file.
- Remove duplicated build step. There is no difference between the jobs,
  so we don't need build job based on the workflow trigger.
- Create & compress the tar archive in one go.
