Provide ExitStatusError
Closes #73125

This is in pursuance of
  Issue #73127 Consider adding #[must_use] to std::process::ExitStatus

In
  MR #81452 Add #[must_use] to [...] process::ExitStatus
we concluded that the existing arrangements in are too awkward
so adding that #[must_use] is blocked on improving the ergonomics.

I wrote a mini-RFC-style discusion of the approach in
  https://github.com/rust-lang/rust/issues/73125#issuecomment-771092741
