although this is not part of EIP 1767
but the hive test cases derived from besu
test cases contains this.
we add this now to pass more test hive.graphql cases
`makeCall` used by GraphQL is another way to setup and call the EVM.
Move it to `transaction/call_evm`.

`estimateGas` used by JSON-RPC is another way to setup and call the EVM,
also used by GraphQL. Move it to `transaction/call_evm`.
This function has too much direct knowledge of details that shouldn't be used
outside transaction handling code, details we need to change when changing the
db and transaction memory layer.
Moving this one exposed quite a bit of abstraction leakage, as it calls
directly to the hexary trie db around `processTransaction`.
It looks like the _intended_ functionality of `estimateGas` is similar to
`rpcDoCall` with the only real difference being to not store the final state.
It looks like the extra stuff in `estimateGas` compared with `doCall` is a
messy workaround for computation not exposing the right API ("don't save final
state") for RPC to use.

Start gathering the functions that call the EVM into one place,
`transaction/call_evm.nim`.
This is first of a series of changes to gather all ways the EVM is called to
one place. Duplicate, slightly different setup functions have accumulated over
time, each with some knowledge of EVM internals. When they are brought
together, these methods will be changed to use a single entry point to the EVM,
allowing the entry point to be refactored, EVMC to be completed, and async
concurrency to be implemented on top. This also simplifies the callers.
First, a helper function used by RPC and GraphQL to make EVM calls without
permanently modifying the account state. `setupComputation` ->
`rpcSetupComputation`.
