Add support for necessary events to be sent regardless of event dispatcher enabled state

[rh101]

Describe your changes

If the event dispatcher is disabled, then necessary events such as EVENT_RENDERER_RECREATED, EVENT_APP_RESTARTING, EVENT_COME_TO_FOREGROUND, and EVENT_COME_TO_BACKGROUND will not be sent, which in certain instances will result in application crashes.

An example case:

1 - event dispatcher is disabled (such as on entering a scene transition)
2 - the app is moved to the background for any reason
3 - the app is then moved back to the foreground
4 - if the EGL context is lost, then it will attempt to recover/restart depending on the configuration (AX_ENABLE_CACHE_TEXTURE_DATA == 1 or AX_ENABLE_RESTART_APPLICATION_ON_CONTEXT_LOST == 1)
5 - since the event dispatcher is still disabled, EVENT_RENDERER_RECREATED (or EVENT_APP_RESTARTING) would never be sent out
