gpu-compute: Add missing initial reg state in WF

Browse Source 
There are two initial scalar register fields that are not initialized in
the wavefront when a task is dispatch. This changeset adds the missing
DispatchId and PrivateSegSize fields. These fields are typically used
when an application is compiled with debug support and are typically not
used in the applications in gem5's test suite.
