Extend the "TraceCall" API so that the state override can be support

[rjl493456442]

Now the eth_callAPI can accept an optional parameter overrides *map[common.Address]account so that the user can customize the states by himself. Would be nice to include this feature in the tracer API too.

Triage discussion: this can be added without making a breaking change, by adding a new field to the input config for that particular call.

hi @rjl493456442 although the feature is been added, could you explain what's the typical use case, could you make an example?

Is there a way to make this functionality accessible on the ethclient.Client interface?
