Misc fixes to TTS settings.

1. Remove an extra PreferenceGroup that was causing some spacing
   issues.
2. Remove the animations when elements resize because this causes
   items to slide around unnecessarily.
3. While we're in the file, lambda-ify some of the older code.

Bug: 77981482
Bug: 79897262
Test: Manually verified.
