[gnome-builder] completion-words: add IdeCompletionWords

[Christian Hergert <chergert src gnome org>]

commit 7cfeb0f2252b524b8a1d060e4cbb508b80bc41cf

    completion-words: add IdeCompletionWords
    
    This subclasses GtkSourceCompletionWords but changes when the provider
    is activated. This avoids activating when we are in comments as that is
    much more likely to miss-activate (such as typing a similar word at the
    end of a line in a comment).
