Change AllocatePersistentBuffer API to just return a pointer if succeed, or nullptr upon failure

Changes the canonical usage pattern from:

void* data = nullptr;
  if (context->AllocatePersistentBuffer(context, sizeof(OpData), &data) ==
      kTfLiteError) {
    return nullptr;
  }
  return data;

to:

return context->AllocatePersistentBuffer(context, sizeof(OpData);
