Fix for bug #34905789
A call to showInputMethodPickerFromClient should be allowed only if the
caller is:
* The system service, as system services should have the privilege to
show any dialogs
* The current IME client, as it was already enabled by the user
* The app on the foreground, as the user cannot distinguish the source
of the request (i.e., foreground vs background app) and might be
mislead by a background app to change settings
* A process with the android.Manifest.permission.WRITE_SECURE_SETTINGS
permission, as it already has the permission to change settings
