Allocate unique stable ids for non-contiguous paintings of an effect
Due to paint order bugs (e.g. crbug.com/1253797), paintings under a
blink effect node may interlace with other paintings. If the effect
node is composited, we'll create multiple cc effect nodes, and
previously they had the same stable id causing duplicated id for render
passes. Now allocate unique stable ids when we create additional cc
effect nodes for a blink effect node.
