[ML] More advanced model snapshot retention options (#56125)
This PR implements the following changes to make ML model snapshot
retention more flexible in advance of adding a UI for the feature in
an upcoming release.

- The default for `model_snapshot_retention_days` for new jobs is now
  10 instead of 1
- There is a new job setting, `daily_model_snapshot_retention_after_days`,
  that defaults to 1 for new jobs and `model_snapshot_retention_days`
  for pre-7.8 jobs
- For days that are older than `model_snapshot_retention_days`, all
  model snapshots are deleted as before
- For days that are in between `daily_model_snapshot_retention_after_days`
  and `model_snapshot_retention_days` all but the first model snapshot
  for that day are deleted
- The `retain` setting of model snapshots is still respected to allow
  selected model snapshots to be retained indefinitely

Closes #52150
