cmd, core, eth: background transaction indexing (ethereum#20302)

* cmd, core, eth: init tx lookup in background * core/rawdb: tiny log fixes to make it clearer what's happening * core, eth: fix rebase errors * core/rawdb: make reindexing less generic, but more optimal * rlp: implement rlp list iterator * core/rawdb: new implementation of tx indexing/unindex using generic tx iterator and hashing rlp-data * core/rawdb, cmd/utils: fix review concerns * cmd/utils: fix merge issue * core/rawdb: add some log formatting polishes Co-authored-by: rjl493456442 <[email protected]> Co-authored-by: Péter Szilágyi <[email protected]>
