fix [#33029] Applying modifier leaks memory

Thanks for Sergey for finding the bug & patching, This fix works a bit differently.
Theres no need to allocate the customdata in the first place - since its written into. So add a flag for vert/edge/face/loop creation functions so they can skip customdata creation.
