RFR: JDK-8293480: IGV: Update Bytecode and ControlFlow Component immediately when opening a new graph [v6]

[Tobias Holenstein]

> The `BytecodeViewTopComponent` and `ControlFlowTopComponent` represent information depending on what graph is open in `EditorTopComponent`. Previously, `BytecodeViewTopComponent` and `ControlFlowTopComponent` did not update its content immediately when a new graph from a different group is opened in `EditorTopComponent`. They also did not update when switching between two tabs of open graph. 
> 
> We missed to `fire()` a `diagramChangedEvent` in the constructor of `EditorTopComponent`. We also need to fire when `BytecodeViewTopComponent` and `ControlFlowTopComponent` are initially opened.
