Tracking eth_simulate issues

[mattsse]

Describe the feature

ref #8281

the new eth_simulate impl still has a few inconsistencies, eg

1. if calls object is missing reth complains, while its not mandatory, here's example test:
   {
   "jsonrpc": "2.0",
   "id": 1,
   "method": "eth_simulateV1",
   "params": [{"blockStateCalls": [{}]}, "latest"]
   }
2. blockStateCalls is also not mandatory:
   {"jsonrpc":"2.0","id":1,"method":"eth_simulateV1","params":[{},"latest"]}
3. calls should return a value returnData reth returns returnValue that is not in the spec
4. logs are returning blockTimestamp which is not in the spec
