[lint] Disable modernize-use-nodiscard (#68354)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/68354
Lint rule: https://clang.llvm.org/extra/clang-tidy/checks/modernize-use-nodiscard.html
This check adds a ton of noise to our diffs. `[[nodiscard]]` is typically only useful when ignoring the return value of a function is a critical error, e.g. for `operator new`.
Test Plan: Verified that the lint does not get triggered
