WidgetComponent is not updated with occlusion culling disabled

LastRenderTime is never updated with occlusion culling disabled, so the widget component will always stop updating.  (see UWidgetComponent::ShouldDrawWidget)
Developers can force updates by TickWhenOffscreen property. however, the performance overhead should not be underestimated.

1. (setup PC VR HMD and controllers)
2. Create a project with VR template
3. Open project settings and uncheck Occlusion culling
4. Start VR preview PIE in VRTemplateMap
5. Press the menu button on left VR controller to open In-game menu
6. Point to the menu items with your right hand

Result:

WidgetComponent updates are disabled, so menu item highlighting, etc. will not work.
