Remove various `has_errors` or `err_count` uses follow up to https://github.com/rust-lang/rust/pull/119895 r? `@nnethercote` since you recently did something similar. There are so many more of these, but I wanted to get a PR out instead of growing the commit list indefinitely. The commits all work on their own and can be reviewed commit by commit.
