Use individual execution counters when calculating retry delay

Individual execution counters were introduced in #34352. However
`#determine_delay` which is used to calculate retry delay still uses the
global counter. This commit fixes it.

+*   Use individual execution counters when calculating retry delay.

+    *Patrik Bóna*
+
 *   Make job argument assertions with `Time`, `ActiveSupport::TimeWithZone`, and `DateTime` work by dropping microseconds. Microsecond precision is lost during serialization.
