Remove non-templated qobject module api registration function

Previously, both templated and non-templated qobject module api
registration functions were provided as public API.  The non-templated
version is identical to the templated version, except that bindings
which access properties of module apis registered with that function
cannot be optimized with v4.

This commit removes the non-templated version of the function.
