It creates x11_display_util.cc/h files and moves the APIs to
get display information using XRANR from DesktopScreenX11 to
share the implementation with Ozone/X11.

'GetXrandrVersion' is to get xrandr version,
'GetFallbackDisplayList' is to get a fallback display and
'BuildDisplaysFromXRandRInfo' is to get a list of displays from
the current screen.

It also moves 'GetICCProfileForMonitor' from DesktopScreenX11
to x11_util.cc.

These APIs are required for Ozone/X11 as well. This change doesn't
bring any behavioral changes.
