Instead, have WXOnActivate() and WXOnLeftClick() with same signatures as
their public API counterparts and just call Activate/LeftClick() from
them for wxDataViewCustomRenderer.

This accomplishes the same thing, but makes it easier to override
behaviour in wx's internal implementations of renderers.
