Add raw configuration change listener updates.

Add raw configuration change listener updates. Letterboxed Activities do
not receive a configuration update when they are repositioned. Listening
to all configuration changes will correctly update folding features.
Change exceptions from hard exceptions to Log.wtf so that we do not
crash on production apps.

Bug: 295785410
Test: Open Samples and open the slim (letterbox) Activities.
