TextEditor: Add missing file to dev package

The public header "textdocumentlayout.h" includes "State" from
KSyntaxHighlighting, so we need to export that.
Since it doesn't have the ".h" extension, it doesn't get exported
automatically either. Add a generic function for adding such special
public header files.
