`nsChildView::GetEditorView()` is called by `TextInputHandlerBase::GetWindowLevel()` which is called when Cocoa requests window level of focused widget. It currently gets widget including focused element (e.g., it may be in a XUL `<panel>`) with `eQueryTextContent` event. However, it requires only the widget (i.e., when a XUL `<panel>` has focused element, the widget for the panel). Therefore, it does not require to flush the layout. However, on macOS, `ContentEventHandler` always flushes layout even with `eQueryContentState` which does not require any layout information. Whether it requires flushing layout or not is considered with `WidgetQueryContentEvent::mNeedsToFlushLayout` but this is set to false only when `IMEContentObserver` notifies widget (and IME) of focus set. At this time, only on macOS, IME caches the layout information, for example, the character coordinates, but we don't have a way to update it. This is the reason why we always flush layout on macOS. Unfortunately, when a menu popup frame is created, widget for the popup is created synchronously. Then, Cocoa retrieves window level of the widget including focused element. But this is unsafe to flush the layout. So, we need to stop flushing layout in this case. Therefore, this patch moves the `#ifdef` from `TextEvents.h` to `IMEContentObserver.cpp`, then, makes `nsChildView::GetEditorView()` use `eQueryContentState` which is the simplest query content event, and finally, sets `mNeedsToFlushLayout` to `false`.
