add report_after_job_retries support for ActiveJob

[modosc]

Description

this pr adds report_after_job_retries support to ActiveJob (configured via config.rails.active_job_report_after_job_retries).

the easiest way to do this would have been to use retry_on in the base ActiveJob class (similar to here) but that's difficult to do properly which is (i think) why the current ActiveJob integration doesn't do it.

instead we can take advantage of the retry_stopped.active_job notification that's published when a job runs out of retries. this makes our setup a single call to ActiveSupport::Notifications.subscribe.

fixes #2499
