* Fix AsyncHooksGetTriggerAsyncId such it corresponds to
async_hooks.triggerAsyncId and not async_hooks.initTriggerId.
* Use an async_context struct instead of two async_uid values.
This change was necessary since the fixing
AsyncHooksGetTriggerAsyncId otherwise makes it impossible to
get the correct default trigger id. It also prevents an invalid
triggerAsyncId in MakeCallback.
* Rename async_uid to async_id for consistency
* Rename get_uid to get_async_id
* Add get_trigger_async_id to AsyncResource class
