Allow state override on eth_estimateGas

[HackProAIT]

Describe the feature

Currently, you can not perform an eth_estimateGas on something that isn't in the 'correct' state as the evm will, correctly, return an error. For example, on an erc20 you may wish to send an approve followed by a transfer call. You can estimate gas for the approve but not the transfer.

Implementation

Add an additional parameter to the end of the request in the same way eth_call does.

Hey @HackProAIT, thanks for this, I didn't know that geth supported state overrides in eth_estimateGas now, but it makes sense.

We are in the middle of a pretty involved refactor of the Hardhat network, so ideally we'd wait until that it's ready before implementing this. But if you think this has some urgency, we might do it before that (it should be pretty straightforward anyway).
