[PyTorch] Remove unused dump() methods in vec headers (#63533)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/63533
These methods don't seem to be used, and they use std::cout, which incurs a small code size overhead on platforms using libstdc++ due to std::__ioinit (see #61500). Seems like we can just delete them?
