feat: pass `skipRandaoVerification` to `processRandao` correctly

[mkermani144]

Motivation

Allow the block production API to skip RANDAO verification of the block.

Description

While skipping RANDAO verification was already implemented, it was not actually used. In other words, the block production endpoint accept such query param, but it didn't pass it to processRandao (the function that verifies RANDAO) correctly.

Fix the issue by passing the skipRandaoVerification to processRandao via some intermediate functions that are called in the process.

Closes #4638

Thanks @mkermani144 for taking a look at this but as noted in https://github.com/ChainSafe/lodestar/issues/4638#issuecomment-3090543719 I don't feel like it makes sense to implement this right now.

I think we should close this
