Previously, TextServicesManager was exposing APIs to system services to
modify spell checker settings. However, Settings application is the only
client of these APIs and there is no need to expose it to all the other
services. Settings app already has the WRITE_SECURE_SETTINGS permission
and can directly update the spell checker settings. Hence, we can remove
these APIs from TSM.
