* Handle cleaning zero-lamport accounts
Handle cleaning zero-lamport accounts in slots higher than the last full
snapshot slot. This is part of the Incremental Snapshot work.
Fixes#18825
* signal to upsert whether reclaims are important
* reclaims_must_be_empty -> previous_slot_entry_was_cached
* UPSERT_RECLAIMS_MUST_BE_EMPTY_FALSE -> UPSERT_PREVIOUS_SLOT_ENTRY_WAS_CACHED_FALSE
* Move transaction sanitization earlier in the pipeline
* Renamed HashedTransaction to SanitizedTransaction
* Implement deref for sanitized transaction
* bring back process_transactions test method
* Use sanitized transactions for cost model calculation
1. Added both options for measuring space usage using total accounts usage and for individual store shrink ratio using an enum. Validator CLI options: --accounts-shrink-optimize-total-space and --accounts-shrink-ratio
2. Added code for selecting candidates based on total usage in a separate function select_candidates_by_total_usage
3. Added unit tests for the new functions added
4. The default implementations is kept at 0.8 shrink ratio with --accounts-shrink-optimize-total-space set to true
