Add multi-device support for BACnet gateway routing (#1279)

Browse Source 
* Expanded Object_List to Object_List[MAX_NUM_DEVICES] array to support per-device objects for virtual remote devices
* Added multi-device iteration for COV handler, device timer, and intrinsic reporting
* Added apps/gateway2 demo application
* When MAX_NUM_DEVICES == 1, behavior is identical to the original implementation
* Conditional compilation with macros ensures no impact on non-gateway applications
