Adding search for dynamic accessibility settings.
The language and input settings are highly dynamic and this change adds search support for that. This category depends on installed IMEs, input devices, user dictionary configuration, etc. We not only compute the right preferences to be indexed but also track related system state in the settings app to rebuild the index if needed. bug:14066763 Change-Id: Ia89d9e35bd79abf8d74614691aedf4ca9b11b6f2
