eth/catalyst: prefix payload id with version (#28246) 

GetPayloadVX should only return payloads which match its version. GetPayloadV2 is a special snowflake that supports v1 and v2 payloads. This change uses a a version-specific prefix within in the payload id, basically a namespace for the version number.
