cmd: Add retesteth command (to support execution and generation of tests via retesteth) (#19631)

* Add retesteth command

* Remove label and insert full version

* mineBlock - break the inner loop when the block is full

* Fixes for touched non-reward accounts, gas limit issues

* Not fail when SendTx has transaction with incorrect RLP

* Fix linter (unnecessary conversion)

* retesteth: add usage string to flag
