Use QWidgetTextControl in the QtQuick1 TextEdit.

QDeclarative1TextEdit and QTextEdit have the same compatbility
requirements so it makes sense they continue sharing the same line
control implementation.  This allows the QtQuick 2 TextInput to diverge
without creating a third variation of QTextControl,
