[OpenMP][NFC] Added DeviceID and Event pointer to __tgt_async_info

Browse Source 
DeviceID is added for some cases that we only have the __tgt_async_info but do
not know its corresponding device id. However, to communicate with target
plugins, we need that information.

Event is added for another way to synchronize.
