Add qt-qrcode recipe for use in settings app

Add a recipe for the qt-qrcode libqrencode wrapper library to allow
using it to display QR codes in the settings app, and update the
settings app dependencies to add it as a dependency. As cleanup,
the qtwebsockets dependency has been dropped from settings since it
no longer requires it.

+Rework library build
+
+Rework qmake files to build libraries out of the quickitem and widget
+code instead of sample programs. This allows using the associated
+classes without copying the source and running afoul of the LGPL
+licensing. Also add pkgconfig file generation to simplify usage, fix
+header installation, and use pkgconfig to pull in libqrencode instead
+of having to clone a copy in-tree and building it.
