Create a new notification object: a lightweight, non-blocking signal carrier used for IRQ delivery and simple wakeups.
The object starts with no bits set and a reference count of one. The returned handle is grantable, so a server can hand it to a client that needs to be woken.
Returns
A notification handle.
Errors
| Code | Condition |

ERR_NOMEM | No free handle slot, or the object could not be allocated |
