Add qmlRegisterType for Composite Types

This is equivalent functionality to registering a composite type in a
qmldir file, a type name in a versioned module is associated with a
given file. This function now allows that to be done easily from C++.

+  \relates QQmlEngine
+
+  This function registers a type in the QML system with the name \a qmlName, in the library imported from \a uri having the
+  version number composed from \a versionMajor and \a versionMinor. The type is defined by the QML file located at \a url. The
+  url must be an absolute URL, i.e. url.isRelative() == false.
+
+  Normally QML files can be loaded as types directly from other QML files, or using a qmldir file. This function allows
+  registration of files to types from a C++ module, such as when the type mapping needs to be procedurally determined at startup.
+
+  #include <QtQml> to use this function.
+
+  Returns non-zero if the registration was sucessful.
