[WIP] feat(genesis): ensure same view of deposits state between CL and EL

[calbera]

Enforce in genesis that CL and EL view of deposits are consistent:

• EL deposit contract genesisDepositsRoot is same as CL's calculated HTR
• EL deposit contract depositCount is same as length of gen deposits provided to CL

TODO:

• Update eth genesis files to include necessary pre-deploy state of EL deposit contract, so that these checks can be validated
