The max number of deposits is in the system contract and is 16 currently.

Should we check that ret is % 76 == 0 here or just accept anything thats returned from the contract?

Note that work on the spec is still ongoing, and we will have some simplifications in soon that will invalidate most of this PR.

I have created a new implementation in #30571 since it is so much simpler now. There was just no point trying to rebase this one.

This is a redo of #29052 based on newer specs. Here we implement EIPs
scheduled for the Prague fork:

- EIP-7002: Execution layer triggerable withdrawals
- EIP-7251: Increase the MAX_EFFECTIVE_BALANCE

This fixes a few issues missed in #29052:

* `requests` must be hex encoded, so added a helper to marshal.
* The statedb was committed too early and so the result of the system
calls was lost.
* For devnet-4 we need to pull off the type byte prefix from the request
data.
