If engine is not active, its settings icon is disabled in
Settings > Language & input > Text-to-speech output screen.
Currently, settings icons for all TTS engines are shown at
the same opacity. This fix dims settings icons of not-selected
engines.
Make sure that more than one TTS engine are installed on the
target, for e.g., Google Text-to-speech Engine and Classic
Text To Speech Engine (SVOX Classic TTS).
Additionally, since setAlpha() is used in multiple places within
Settings package, moved DISABLED_ALPHA declaration to Utils.java
in order to have single point of reference.

The issue is that Fragment.setVoiceDataDetails can
be called before Fragment.getView. We guard against this
issue. No thread visibility issues here because both functions
are called on the UI thread.
