Investigate whether to remove ethereumjs-abi in favor of @metamask/abi-utils

[mikesposito]

The ethereumjs-abi includes ethereumjs-util in dependencies. We should see if we can substitute it with our own package @metamask/abi-utils across the dep tree

Ok we definitely need to replace ethereumjs-abi with @metamask/abi-utils otherwise we can't remove old (pre v8) ethereumjs-utils which is required to fully replace secp256k1 implementation with the noble implemenations.

Besides the direct dependency in metamask-crx, this goes away after updating @metamask/eth-sig-util to latest (#15906)

[adonesky1]

Yes that's right @mikesposito . Just wanted to state that we do need to do this since this ticket is an "investigation" ticket

[adonesky1]

Going to create a ticket to replace ethereumjs-abi with @metamask/abi-utils in metamask-crx since the other cases are covered by an existing ticket.
