Fix T102966: Curves editmode selection drawing not stable / flickering
Issue was the lifetime of GPUVertFormat & GPUVertAttr. Both need to be static in the function to be persistent here (and handled appropriately). Was an error in rB319ee296fd0c. Maniphest Tasks: T102966 Differential Revision: https://developer.blender.org/D16704
