EIP-7002: EL Triggerable Exits

[macladson]

Description

EIP -> https://eips.ethereum.org/EIPS/eip-7002

Was confirmed for Electra in latest ACD consensus call.
This will require some coordination from EL teams in order to do testing, etc.

Implementation

As per the EIP, the flow is:

• New operation ExecutionLayerExit
• Will show up in ExecutionPayload as an SSZ List bound by length MAX_EXITS_PER_BLOCK
• New function in process_execution_layer_exit that has similar functionality to process_voluntary_exit but that can fail validations (e.g. validator is already exited) without the block failing (similar to deposit coming from EL)
• process_execution_layer_exit called in process_operations for each ExecutionLayerExit found in the ExecutionPayload

There was strong agreement for inclusion? At this point is okay to spend dev resources on it for sure, but I would refrain from merging it into unstable/electra branch for at least 2-3 ACDCs

For now just going off of this PR/commit. My aim is to keep these issues updated as things change

It sounded like EL teams had already OK'd 6110 and 7002 on the last ACDE

but I would refrain from merging it into unstable/electra branch for at least 2-3 ACDCs

Seems reasonable!
