[UE-168360] User can create a transition from a state into the entry state * Relinking multiple transitions (transition nodes at once) when none of the transition nodes is selected. * Selective relinking in case a subset of the transition nodes on a transitions are selected. * Special case handling for transitions from entry state (they don't have a transition node connected). * Drawing circle indicator around the arrow head in case the mouse cursor is approaching the transition. * Hovering the arrow head of a transition highlights it by filling the circle with solid orange color and turning the arrow black. * Ending the relink operation in empty space or the entry node will cancel the relink operation. * Fixed bug that prevents creating new transitions ending in an entry state. #jira https://jira.it.epicgames.com/browse/UE-136096 #jira https://jira.it.epicgames.com/browse/UE-168360 #preflight 636a169963037c10262bc421 [CL 23025287 by benjamin jillich in ue5-main branch]
