wxPoint_Destroy declared in kwx_glue.h but implemented as wxPoint_Delete in kwx_extra.cpp

[Randalphwa]

Bug

kwx_glue.h line 5089 declares:

void wxPoint_Destroy(TSelf(wxPoint) pObject);

But kwx_extra.cpp line 1128 still has the old name:

EXPORT void wxPoint_Delete(void* pObject)

The implementation needs to be renamed from wxPoint_Delete to wxPoint_Destroy to match the header.

Impact

Linker error: undefined symbol wxPoint_Destroy when linking against libkwxFFI.a.

Discovered while updating kwxGO bindings to the latest kwxFFI.
