Motivation unicode-org/icu4x#4048

This PR resolves a common edge case where users attempting to manually track `std::panic::Location`s of their callers in their `Error` types end up with irrelevant locations inside of `std`.

The main concern with this approach that I'm aware of is that `#[track_caller]` increases the stack sizes of the functions it is applied to, though I think this is a non-issue since we already have `#[track_caller]` on `Result`'s `FromResidual` impl which is used far more frequently than any of these APIs when converting errors between different types. This change brings these functions in line with that impl.
