sway/tree: Simplify sway_node teardown

Browse source 
A sway_node may end up being referenced in either a queued transaction,
pending transaction or as a dirty node. To manage this, the transaction
system has been responsible for destroying containers, workspaces and
outputs at the end of their last referenced transaction.

This significantly complicates the teardown flow of surfaces and
outputs. Instead, remove the node from transactions and dirty lists so
that the callsite can remove and free the node immediately.
