Pull request description:

  Work decoupled from #28574. Brother of #28894.

  Includes two different, yet interconnected, performance and code improvements to the zap wallet transactions process.

  1) As the goal of the `ZapSelectTx` function is to erase tx records that match any of the inputted hashes. There is no need to traverse the whole database record by record. We could just check if the tx exist, and remove it directly by calling `EraseTx()`.

  2) Instead of performing single write operations per removed tx record, this PR batches them all within a single atomic db txn.

  Moreover, these changes will enable us to consolidate all individual write operations that take place during the wallet migration process into a single db txn in the future.
