No real changes, just clean up wxCustomRendererObject in Cocoa wxDVC.

The variables tableColumn and item are unneeded in this class so remove them.

Use static_cast<>s instead of C casts.

Avoid repeating oneVeryLongVariableName->anotherEvenLongerVariableName->
somethingElse->andSoOn multiple times, temporary variables are allowed in C++.

Also don't call wxDataViewCustomRenderer::GetSize() twice unnecessarily.
