[NFCI] Explicitly delete unused copy constructor and assign copy for VPInterleavedAccessInfo (llvm#134755)

VPInterleavedAccessInfo has a defined destructor freeing memory, but no
explicitly defined copy constructor or copy assignment op. These are not
used, so this patch marks them as deleted to avoid usage of the
implicitly defined implementations.
