stage: introduce stage_node_[sg]et_position()
Leaving the existing node aabb semantics as both sizing and placing the
node relative to the stage size and its center, add a simple means of
statefully shifting the aabb.
When the position is left unset, it's 0,0, and effectively a noop leaving
the aabb to exclusively size and place the node. If you treat the aabb
as purely sizing the node, treating it as centered at 0,0 then you can
exclusively use this position api for placement of the node.
