Plumb display density to HWUI through ActivityThread.
Whenever an activity's configuration is updated, then tell
HardwareRenderer about it. That way, visualizating frame info does not
need to learn the display density from SurfaceFlinger, which reduces the
native-side api surface for displays.
For now, this method is kept hidden and will be stabilized when
HardwareRenderer's apis are stabilized for Mainline inclusion.
