libhsakmt: add open SMI event handle

Browse Source 
System Management Interface event is read from anonymous file handle,
this helper wrap the ioctl interface to get anonymous file handle for
GPU nodeid.

Define SMI event IDs, event triggers, copy the same value from
kfd_ioctl.h to avoid translation.
