bcachefs: Kill support for !BTREE_NODE_NEW_EXTENT_OVERWRITE()

Browse source

bcachefs has been aggressively migrating filesystems and btree nodes to
the new format for quite some time - this shouldn't affect anyone
anymore, and lets us delete a _lot_ of code. Also, it frees up
KEY_TYPE_discard for a new whiteout key type for snapshots.
