EIP-3860: Limit and meter initcode

Impact

TXN_DATA, likely
- the canonical place where to verify that a transaction's INIT_CODE_SIZE is ≤ 49152 (i.e. 0xC000)
- also where to compute the ceiling computation for ⌊ TX_INIT_CODE_SIZE / 32 ⌋
OOB (extra check for CREATEE/CREATE2 instructions, likely aborting condition, to be verified)
- likely best place to check for the upper bound on init code size
STP (pricing of CREATE/CREATE2)
- likely best place to compute the relevant floor
HUB (CREATE/CREATE2 instruction processing)
- probably unaffected, except maybe in its interfaces with OOB/STP

Notes

The RLP_TXN module seems like it would be unaffected.

This throws an exception according to

• the execution spects: https://github.com/ethereum/execution-specs/blob/e4d7b402a7bda2812e1723642b99614fcdd55193/src/ethereum/shanghai/vm/instructions/system.py#L83
• the EIP: https://eips.ethereum.org/EIPS/eip-3860

But it's an aborting condition according to:

• the EYP: https://ethereum.github.io/yellowpaper/paper.pdf

TODO

• raise an issue on the EYP repo

Test vectors

• existing testvectors for deployment (tx/int. tx)
• aborting condition tests
