feat: Speed up transaction execution

[PhilWindle]

This PR make a number of optimisation related to the speed up of transaction execution. Namely:

1. We don't re-initialise the instruction set mapping with each instruction decode.
2. We now compute public bytecode commitments at the point of receiving a contract and persist them, meaning they don't need to be computed at the point of execution.
3. We only store and iterate opcode and program counter tally information when in debug.
4. Function names are also cached at the point contract artifacts are shared with the node.
5. World state status summary and previous block archive roots are cached to reduce the impact on the world state DB whilst execution is taking place.
