Include head_payload_status in ForkChoiceView comparison

The early exit check in recompute_head_at_slot compared only
head_block_root and checkpoints. When on_execution_payload changed
the payload status from Empty to Full without changing the head root,
the CachedHead was not updated. Add head_payload_status to
ForkChoiceView so the change is detected.
