`Result::map_err` does not have `#[track_caller]`, so using it will set the caller information to the parent `fn trace` (rather than the original caller).

Motivation
We currently lose
#[track_caller]information when ourimpl<T> Traceable<T> for Result<T>impl is used, due to the use ofResult::map_errSolution
Write a manual
matchexpression, so that we correctly propagate caller information.
