remove EIP-7907

[tersec]

Effectively revert and/or don't merge:

• EIP: Implement EIP-7907 #3380

Because per discussion in today's ACD call, https://notes.ethereum.org/@ethpandaops/fusaka-devnet-3 has removed it from devnet-3 and from Fusaka overall. Presumably https://eips.ethereum.org/EIPS/eip-7607 will reflect this shortly.

[tersec]

it was never merged, no need for separate issue
