drm/amdkfd: Add wave control operation to debugger
The wave control operation supports several command types executed upon
existing wave fronts that belong to the currently debugged process.
The available commands are:
HALT - Freeze wave front(s) execution
RESUME - Resume freezed wave front(s) execution
KILL - Kill existing wave front(s)
