Subject: [PATCH] Support flagNoPersonalizedLearning in layout XML

In my previous CL [1] a new flag IME_FLAG_NO_PERSONALIZED_LEARNING
was added for EditorInfo.imeOptions.  What was missed in the
previous CL is that new flag definition for layout XML and as a
result currently IME_FLAG_NO_PERSONALIZED_LEARNING is the only
IME option flag that cannot be specified in layout XML.

For instance, EditorInfo.IME_FLAG_FORCE_ASCII can be specified as
follows.

 <EditText
     android:id="@+id/edittext_force_ascii"
     android:layout_width="match_parent"
     android:layout_height="wrap_content"
     android:imeOptions="actionSend|flagForceAscii" />

With this CL, application developers can specify
IME_FLAG_NO_PERSONALIZED_LEARNING as follows.

 <EditText
     android:id="@+id/edittext_no_personalized_learning"
     android:layout_width="match_parent"
     android:layout_height="wrap_content"
     android:imeOptions="actionSend|flagNoPersonalizedLearning" />
