format macro argument parsing fix When the character next to `{}` is "shifted" (when mapping a byte index in the format string to span) we should avoid shifting the span end index, so first map the index of `}` to span, then bump the span, instead of first mapping the next byte index to a span (which causes bumping the end span too much). Regression test added. Fixes #83344

// check-fail
fn main() {
println!("{}\
"); //~^ ERROR: 1 positional argument in format string, but no arguments were given
}
