Default zoom was never read from chrome://settings

The fix basically includes reading default zoom percent of a tab  from a helper function in zoom_controller.

BUG=427440

TESTs = Go to chrome://settings
              Expand to Webcontents under Advanced Settings
              Change the default Zoom percentage
              Expected result: All the open tabs would be changed to that particular zoom   value and the "Actual Size" under View menu would be disabled.
