Create-snapshot check if slot is available on startup (#25329) 

* Add a check during ledger-tool create-snapshot startup to see if the snapshot slot is available

* check all slots from the start to snapshot_slot during load_bank_forks

* unwrap_or_default incremental snapshot slot before comparison

* Improve error messages on missing or not full slots
