Call eth_callBundle allow to defined state on the selected transaction

[hugo082]

In order to allow an easier transaction simulation via the eth_callBundle method, we introduce a new parameter stateTransactionHash that should be in the stateBlockNumber child. If this parameter is provided, we will execute all transactions from index 0 to the state transaction index (included).

Example

• Chain:
  • Block 0xA
    • Trx 0x0
    • Trx 0x1
    • Trx 0x2
  • Block 0xB
    • Trx 0x3
    • Trx 0x4
    • Trx 0x5

A call to eth_callBundle with:

• stateBlockNumber=0xA and stateTransactionHash=0x4 will result to a state at the end of the transaction 0x4
• stateBlockNumber=0xA and without stateTransactionHash will result to a state at the end of the block 0xA
• stateBlockNumber=0xA and any stateTransactionHash different than 0x3, 0x4 or 0x5 is invalid

I will work on it to fix tests, can you just give me some feedback to confirm the chosen solution? Maybe there is a more efficient way to implement this feature? 🚀

This will be too much of a dos vector to have enabled by default. If it's something you need it should be behind a feature flag
