Fix thread panic when "unreachable" SpawnedTask code is reachable. (a…

…pache#12086)

* test: demonstrate that the unreachable in SpawnedTask is reachable

* chore: use workspace tokio and add feature

* fix(12089): SpawnedTask will no longer panic during shutdown

* chore(12089): add new error type for JoinError

* refactor(12089): handle join error when using SpawnedTask::join_unwind

* Revert "chore: use workspace tokio and add feature"

This reverts commit 3010288.

* refactor(12089): update test to avoid the looping and global (to package tests) panic hook manipulation

* refactor(12089): make single conditional for unwind vs no-unwind, and update test for cancellation error
