drm: make drm-active- stats optional

Browse Source 
When memory stats is generated fresh everytime by going though all the
BOs, their active information is quite easy to get. But if the stats are
tracked with BO's state this becomes harder since the job scheduling
part doesn't really deal with individual buffers.

Make drm-active- optional to enable amdgpu to switch to the second
method.
