Remove execution dependency from core module in consensus/types

[macladson]

Issue Addressed

#8652

Proposed Changes

This moves the ExecutionBlockHash from the execution module to the core module. This allows core to not depend on the execution module, and the ExecutionBlockHash is a pretty core part of our types so I think it makes sense.

Additional Information

Ideally we would pull this type from alloy, but I think with our specific requirements, particularly around tree_hash and ssz, that might not be viable.
