Hayden Stainsby b51aa8f6f9 io: add track_caller to public APIs (#4793) ...

Functions that may panic can be annotated with #[track_caller] so that
in the event of a panic, the function where the user called the
panicking function is shown instead of the file and line within Tokio
source.

This change adds #[track_caller] to all the non-unstable public io APIs
in the main tokio crate where the documentation describes how the
function may panic due to incorrect context or inputs.

Additionally, the documentation for `AsyncFd` was updated to indicate
that the functions `new` and `with_intent` can panic.

Tests are included to cover each potentially panicking function. The
logic to test the location of a panic (which is a little complex), has
been moved to a test support module.
