Fix EP0 in dynamic bridge app (#23179)

* Fix EP0 in dynamic bridge app Currently this conflicts with EP0 Descriptor clusters, we register an override that can't provide EP0 values and it vectors into that * Instead just ignore desciptor clusters * remove dead code * Fix style * Update main.cpp remove constant * force add a descriptor cluster to every device
