drm/amdkfd: Remove unused old debugger implementation

Cleanup the kfd code by removing the unused old debugger
implementation.
The address watch was only ever implemented in the upstream
driver for GFXv7 (Kaveri). The user mode tools runtime using
this API was never open-sourced. Work on the old debugger
prototype that used this API has been discontinued years ago.
Only a small piece of resetting wavefronts is kept and
is moved to kfd_device_queue_manager.c.
