EVM instruction gas metrics + intrinsic gas table

[winsvega]

We need to define this tables for each fork like in evmone if not defined in eels already
https://github.com/ethereum/evmc/blob/a0090c7d20f92b04b57e2ee1602fda4dedd97dd5/lib/instructions/instruction_metrics.c

so we can calculate the gas usage of series of opcodes.
and intrinsic gas like cost of access list, warm touch, cold touch, storage touch, storage reset from x to y.

all this has gas costs that would be good to have defined so that in test we can define how much gas expected to be spent exactly and where it comes from.

Check gas_costs functions that are returned by each fork in https://github.com/ethereum/execution-spec-tests/blob/main/src/ethereum_test_forks/forks/forks.py, to see if this is what you had in mind.

Oh, I missed that. Let me check.

I see. it is not implemented. the only gas costs are for Frontier and only for a limited set of operations
