base: Move UI code out of SysInfo.

This moves GetPrimaryDisplayDimensions() and DisplayCount()
out of base and into a new DisplayUtils class (currently
alongside the metrics code, since that's the only place that
they're called).  These methods add a GDK dependency that
prevents Chrome OS from including process_util (which
depends on SysInfo) in its libchrome library.
