hg: openjfx/2u/dev/rt: RT-29975: key to lookup cached styles depended on which parent nodes had parent stylesheets. This led to cache misses because an identical scene-graph would have a different key simply because the node instances were different. Instead, the key can just use the list of parent stylesheets.

stylesheets. This led to cache misses because an identical scene-graph would 
have a different key simply because the node instances were different. Instead,
