Add a static variant of qmlRegisterInterface()

qmlRegisterInterface() should not be called procedurally, for the same
reason that qmlRegisterType() should not be called procedurally.

Also, add URI and major version parameters to qmlRegisterInterface(),
and deprecate the typeName parameter. We want to identify which import
an interface belongs to.
