Remove temp. code to disable "Languages and Settings" on OS X.

The "Languages and Settings" menu item should not be present in the first place in the spellcheck context menu on OS X.

I'll remove the menu item in a followup CL but in the meantime we can remove the code that specifically disables the command on Mac. In the interim having it enabled doesn't do any harm.

TEST=None
