Settings app changes spell checker settings directly without TSM APIs

Browse Source 
Previously, Settings application was using TextServicesManager APIs to
update any of the spell checker settings (i.e., enabled/disabled, spell
checker, subtype). Since these APIs are used only by the Settings
application, there is no need to expose it to other services and the
Settings application can directly write them to secure settings since it
has the WRITE_SECURE_SETTINGS permission.

Bug: 62950392
Test: Manually as follows.
      1. Build and flash an OS image.
      2. Complete the setup wizard (if any).
