[Mac]: Make dictionary context menu item use system settings for whether to launch Dictionary.app or show a panel.

BUG=65537, 121917
TEST=Open Dictionary.app's preferences and change "Contextual Menu:" to "Open Dictionary Panel".
Select a word in the web content area, right click and choose "Look Up in Dictionary". The
dictionary panel should appear with the overlay text positioned correctly over the word.
Change the setting back in Dictionary.app and observe that choosing "Look Up in Dictionary"
brings up Dictionary.app in that case.
