Fix GpuProcessTransportFactory destructor crash

https://codereview.chromium.org/2297473002 changed a raw pointer in
GpuProcessTransportFactory into a unique_ptr, which caused some
additional shutdown behavior (destroying map entries) that was not
there before the patch.

PerCompositorData depends on SurfaceManager existing (to unregister
begin frame sources from ~Display).  So, SurfaceManager's lifetime
should exceed the lifetime of all Displays.
