[jfx-tests] RFR: 8316807: Exclude 3D subscene perspective camera picking tests

[Jayathirth D V]

While debugging subscene picking tests it was identified that in subscene mouse events are not captured when we click on area where nothing is drawn or filled.
All the picking tests actually click on these null points and expect a mouse event. This causes TimeoutExpiredException when subscene is used.

Also we add borders to subscene and expect it to return same pickresults as in scene.
Removed borders for subscene and also added mouse event handler on scene itself. Adding mouse event handler on scene resolves TimeoutExpiredException but still the subscene tests continue to fail.

Currently we are trying to stabilize as many tests as possible to use these automated tests for Metal pipeline implementation. To continue more investigation regarding these failures i have created : https://bugs.openjdk.org/browse/JDK-8317309 and to update subscene specification for difference in how mouse event are handled i have created : https://bugs.openjdk.org/browse/JDK-8317310

We should problem list these tests and continue debugging as part of separate bug : https://bugs.openjdk.org/browse/JDK-8317309
