  1. sql/gcjob: retry failed GC jobs 

    In the previous implementation, failed GC jobs were not being retried
regardless whether the failure is permanent or transient. As a
result, a GC job's failure risked orphaned data, which cannot be
reclaimed.

This commit adds a mechanism to retry failed GC jobs that are not
permanent. No limit is set on the number of retries. For the time
being, the failure type is determined based on the failure
categorization of schema-change jobs. This behavior is expected to
change once exponential backoff mechanism is implemented for failed
jobs (cockroachdb#44594).

Release note: None

Fixes: cockroachdb#65000
