…ealed nullifiers (#8895) * Adds new column family for [spent_out_loc] -> [spending_tx_loc] with a read method and an update to `prepare_spending_transparent_tx_ids_batch()` for maintaining it when committing blocks to the finalized state. Adds TODOs for remaining production changes needed for issue #8837. * add spending tx ids for spent outpoints to non-finalized chains * adds a `spending_transaction_hash()` read fn for the new column family * Adds a `TransactionIdForSpentOutPoint` ReadRequest and a `TransactionId` ReadResponse * Updates snapshots, removes outdated TODOs, moves a TODO. * Clarifies `spent_utxos` field docs, fixes an assertion * import TypedColumnFamily from `finalized_state` instead of from the crate. * adds db format upgrade for spent outpoints -> tx hash * adds revealing tx ids for nullifiers in finalized and non-finalized states * updates nullifiers column families to include revaling transaction locations in db format upgrade * Renames new read state request to `SpendingTransactionId` and updates its type to a `Spend` enum * refactor db format upgrade and prepare_nullifiers_batch() to use ZebraDb instead of DiskDb, checks cancel_receiver before every db operation * Adds acceptance test for checking that the finalized state has spending transaction ids * Adds variant docs to zebra_state::request::Spend enum * Updates Zebra book with the latest changes to the rocks db column families * Updates acceptance test to check non-finalized state * adds a few log messages to the acceptance test, reduces frequency of logs for progress updates * fixes docs lint and skips test when there is no cached state * Avoids returning genesis coinbase tx hash when indexes are missing * Adds `indexer` compilation feature in zebra-state and build metadata in db format version file * stops tracking new indexes in finalized state when feature is unselected * stops tracking new indexes in non-finalized state when indexer feature is unselected * condenses imports * - adds build metadata when writing db version file, if any. - adds the build metadata to the db version file before adding indexes. - deletes indexes when running without the `indexer` feature * Replaces dropping cf with deleting range of all items to avoid a panic when trying to open the db with that column family. * Fixes lint, avoids reading coinbase transactions from disk * updates db column families table * Document need for having an indexed cached state and use a multi-threaded tokio runtime in has_spending_transaction_ids test * fixes call to renamed `future_blocks` test fn * improves test logs and fixes a disk format deserialization bug * Replaces a new expr with a previously existing constant, fixes typo
