Currently, the Delight3DictionaryFacilitator sets a boolean flag when the top
suggestion score exceeds the auto-correction threshold. This flag is used to
trigger auto-correction of the typed word. Also, the existing logic assumes
that if allowsToBeAutoCorrected then the word is invalid, which is no longer
true after we stopped using whitelists.

Make mSuggest final and give DictionaryFacilitator the
responsibility to manage dictionary loading state.
This can simplify the logic to decide how to deal with
additional dictionaries when loading settings or language
