Rollup merge of #82255 - nhwn:nonzero-err-as-bug, r=davidtwco

Make `treat_err_as_bug` Option<NonZeroUsize>

`rustc -Z treat-err-as-bug=N` already requires `N` to be nonzero when the argument is parsed, so changing the type from `Option<usize>` to `Option<NonZeroUsize>` is a low-hanging fruit in terms of layout optimization.
