Get provider_job_id from DelayedJob

When queueing with DelayedJob, get the id of the job instance and report
it back to ActiveJob as provider_job_id.

activejob/CHANGELOG.md

+*   Allow `DelayedJob` to report id back to `ActiveJob::Base` as
+    `provider_job_id`.
+
+    Fixes #18821.
+
+    *Kevin Deisz*
+
 *   `assert_enqueued_jobs` and `assert_performed_jobs` in block form use the
     given number as expected value. This makes the error message much easier to
     understand.
