miner: suspend miner if node is syncing (#27218)
Drop the notions of uncles, and disables activities while syncing - Disable activities (e.g. generate pending state) while node is syncing, - Disable empty block submission (but empty block is still kept for payload building), - Drop uncle notion since (ethash is already deprecated)
