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 flagChrisChinchilla-patch-3
