Remove remaining doc references to StyledAttributes.

It appears StyledAttributes was renamed to TypedArray
prior to fw 1.0.  Leaving references to the old name
around in the public docs is confusing.

Deliberating leaving...
   tests/coretests/src/android/widget/LabelView.java
... as is - it's clearly unused.
