Remove disablement of jQuery.IME on VisualEditor surfaces

The compositionstart trigger in ContentEditableEntry#replaceTextAtSelection
causes ve.ce.Surface#handleInsertion to run, and this appears to be all the
VisualEditor integration we need. But if we later decide we need custom
TextEntry class, see the earlier revision at
https://gerrit.wikimedia.org/r/#/c/264577/3 .
