[issue35810] Object Initialization does not incref Heap-allocated Types

Sorry, morning coffee didn't kick in yet I guess. ;-)  My actual wish is to make all types heap allocated and eliminate the statically allocated ones.  So, Py_TPFLAGS_HEAPTYPE would be set on all types in that world.  That is a gigantic task, affecting near every Python extension type.  Too huge for even a nutty person like me to imagine doing in the near term.  So, sorry for potentially derailing discussion here.

I agree with comments made by Stefan Behnel and Petr Viktorin.  There is a small risk to cause problems (i.e. serious memory leaks in a previously working program).  However, as Petr says, the extension in that case is broken and it is not hard to fix.  Eddie has provided examples for what changes are needed.

I think if we properly communicate the change then it is okay to merge the PR.
