evm t8n to use ExecuteBlockEphemerally api (#4642) 
* evm t8n tool to use ExecuteBlockEphemerally api (#4512)

* fix to set V, R, S in legacy transaction

* fix to dump post-execution alloc for evm t8n

* close tx in evm t8n

* populate current difficulty and gas used in output result

- update the ExecutionResult to include corresponding info (like
  Difficulty/GasUsed)

* initial attempt at migrating 'evm t8n' to use ExecuteBlockEphemerally

* using ExecutionResult in ExecuteBlockEphemerally

* bypass validations and integrate with EphemeralExecResult

* fixing output of 'evm t8n'

- remaining bits are "stateRoot" in results.txt and "balance" field for one account in
  alloc.txt (for testdata=1)

* get ExecuteBlockEphemerally to accept getTracer lambda

* fix build failure

* test cases for evm t8n

* more test cases for evm t8n

* fix stateRoot computation in evm t8n

* remove reward argument, as EBE itself takes care of it

* final cleanups for migration to using ExecuteBlockEphemerally

* change EBEforBSC to match EBE

* fix linter issues

* manually revert an unwanted diff

* avoid calculating ReceiptHash twice

* linter check

* minor correction

* remove unnecessary logic in EBEforBsc

* fix integration tests

* fix build

EIP-2930 testing

This test contains testcases for EIP-2930, which uses transactions with access lists.

Prestate

The alloc portion contains one contract (0x000000000000000000000000000000000000aaaa), containing the following code: 0x5854505854: PC ;SLOAD; POP; PC; SLOAD.

Essentialy, this contract does SLOAD(0) and SLOAD(3).

The alloc also contains some funds on 0xa94f5374fce5edbc8e2a8697c15331677e6ebf0b.

Transactions

There are three transactions, each invokes the contract above.

  1. ACL-transaction, which contains some non-used slots
  2. Regular transaction
  3. ACL-transaction, which contains the slots 1 and 3 in 0x000000000000000000000000000000000000aaaa

Execution

Running it yields:

dir=./testdata/8 && ./evm t8n --state.fork=Berlin --input.alloc=$dir/alloc.json --input.txs=$dir/txs.json --input.env=$dir/env.json --trace && cat trace-* | grep SLOAD
{"pc":1,"op":84,"gas":"0x484be","gasCost":"0x834","memory":"0x","memSize":0,"stack":["0x0"],"returnStack":[],"returnData":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}
{"pc":4,"op":84,"gas":"0x47c86","gasCost":"0x834","memory":"0x","memSize":0,"stack":["0x3"],"returnStack":[],"returnData":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}
{"pc":1,"op":84,"gas":"0x49cf6","gasCost":"0x834","memory":"0x","memSize":0,"stack":["0x0"],"returnStack":[],"returnData":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}
{"pc":4,"op":84,"gas":"0x494be","gasCost":"0x834","memory":"0x","memSize":0,"stack":["0x3"],"returnStack":[],"returnData":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}
{"pc":1,"op":84,"gas":"0x484be","gasCost":"0x64","memory":"0x","memSize":0,"stack":["0x0"],"returnStack":[],"returnData":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}
{"pc":4,"op":84,"gas":"0x48456","gasCost":"0x64","memory":"0x","memSize":0,"stack":["0x3"],"returnStack":[],"returnData":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}

Simlarly, we can provide the input transactions via stdin instead of as file:

dir=./testdata/8 \
  && cat $dir/txs.json | jq "{txs: .}" \
  | ./evm t8n --state.fork=Berlin \
     --input.alloc=$dir/alloc.json \
     --input.txs=stdin \
     --input.env=$dir/env.json \
     --trace  \
  && cat trace-* | grep SLOAD

{"pc":1,"op":84,"gas":"0x484be","gasCost":"0x834","memory":"0x","memSize":0,"stack":["0x0"],"returnStack":[],"returnData":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}
{"pc":4,"op":84,"gas":"0x47c86","gasCost":"0x834","memory":"0x","memSize":0,"stack":["0x3"],"returnStack":[],"returnData":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}
{"pc":1,"op":84,"gas":"0x49cf6","gasCost":"0x834","memory":"0x","memSize":0,"stack":["0x0"],"returnStack":[],"returnData":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}
{"pc":4,"op":84,"gas":"0x494be","gasCost":"0x834","memory":"0x","memSize":0,"stack":["0x3"],"returnStack":[],"returnData":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}
{"pc":1,"op":84,"gas":"0x484be","gasCost":"0x64","memory":"0x","memSize":0,"stack":["0x0"],"returnStack":[],"returnData":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}
{"pc":4,"op":84,"gas":"0x48456","gasCost":"0x64","memory":"0x","memSize":0,"stack":["0x3"],"returnStack":[],"returnData":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}

If we try to execute it on older rules:

dir=./testdata/8 && ./evm t8n --state.fork=Istanbul --input.alloc=$dir/alloc.json --input.txs=$dir/txs.json --input.env=$dir/env.json 
INFO [01-21|23:21:51.265] rejected tx                              index=0 hash="d2818d…6ab3da" error="tx type not supported"
INFO [01-21|23:21:51.265] rejected tx                              index=1 hash="26ea00…81c01b" from=0xa94f5374Fce5edBC8E2a8697C15331677e6EbF0B error="nonce too high: address 0xa94f5374Fce5edBC8E2a8697C15331677e6EbF0B, tx: 1 state: 0"
INFO [01-21|23:21:51.265] rejected tx                              index=2 hash="698d01…369cee" error="tx type not supported"

Number 1 and 3 are not applicable, and therefore number 2 has wrong nonce.
