drm/amdkfd: add debug device snapshot operation
Similar to queue snapshot, return an array of device information using
an entry_size check and return.
Unlike queue snapshots, the debugger needs to pass to correct number of
devices that exist. If it fails to do so, the KFD will return the
number of actual devices so that the debugger can make a subsequent
successful call.
