Update "limit-ledger-size" to use DeleteRange for much faster deletes (#7515)

Browse Source 
* Update "limit-ledger-size" to use DeleteRange for much faster deletes

* Update core/src/ledger_cleanup_service.rs

Co-Authored-By: Michael Vines <mvines@gmail.com>

* Rewrite more idiomatically

* Move max_ledger_slots to a fn for clippy

* Remove unused import

* Detect when all columns have been purged and fix a bug in deletion

* Check that more than 1 column is actually deleted

* Add helper to test that ledger meets minimum slot bounds

* Remove manual batching of deletes

* Refactor to keep some N slots older than the highest root

* Define MAX_LEDGER_SLOTS that ledger_cleanup_service will try to keep around

* Refactor compact range
