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)
