Introduce qmlRegisterModule()

This is particularly useful for keeping the versions of related modules in
sync. For example, when QtQuick.Controls introduces new types or revisions
and bumps up the minor version, qmlRegisterModule() can be used to make the
same version available for QtQuick.Controls.Styles in case it doesn't have
new types or revisions to register.

[ChangeLog][QtQml] Introduced qmlRegisterModule() that can be used to
make a certain module version available, even if no types or revisions
are registered for that version.
