Do you think it's big and focused enough to factor it into a discrete method?

Sorry to come back to you on this, but rather than passing whole CallParameter and BlockHeader, we can pass gas limits only, it would make it even more focused

no worries, it makes sense again.

I wonder if it is more clear to use rpcGasCap > 0 as the first test.
Basically, we start by asking if the user have a configured rpcGasCap, and depending on this user choice, we can check other options.

I understand it could be subjective, I prefer that user provided gas limit drives the choice.

PR description
A recent PR (#6978) made the optional
rpc-gas-capconfig to always override the gas cap used for tx simulation, when specified, but while this could be good foreth_call, it does not work well with calls likeeth_estimateGaswhen the gas cap could be based on what use provided or the sender balance, and it also diverging from what Geth does.This PR align the gas cap calculation used during tx simulation, to what Geth does, with only a little difference, the algorithm is the following:
rpc-gas-cap, in which case we return the latterrpc-gas-capif configured, otherwise use the block gas limit^.^ in this case Geth use
