Unwrap payload bid (#14035)

* engine GetPayload returns entire response * deprecate PayloadValueTo(Gwei|Wei) * return entire bid from builder getter * get bid value from api bid (not ExecutionData) * plumb bid and bundle through BuildBlockParallel * rm ValueInGwei * removing wei/gwei fields from the payload wrappers * commentary around the little-endian situation * finish the job in BuildBlockParallel * light self-review cleanup * fix spectest mock * restore engine timeout * lint fixes * de-duplicate imports * remove errant comment * James feedback --------- Co-authored-by: Kasey Kirkham <kasey@users.noreply.github.com>
