James Liu 210979f631 Fix panicking on another scope (#6524)
# Objective
Fix #6453. 

## Solution
Use the solution mentioned in the issue by catching the unwind and dropping the error. Wrap the `executor.try_tick` calls with `std::catch::unwind`.

Ideally this would be moved outside of the hot loop, but the mut ref to the `spawned` future is not `UnwindSafe`.

This PR only addresses the bug, we can address the perf issues (should there be any) later.

bevy_tasks

A refreshingly simple task executor for bevy. :)

This is a simple threadpool with minimal dependencies. The main usecase is a scoped fork-join, i.e. spawning tasks from a single thread and having that thread await the completion of those tasks. This is intended specifically for bevy as a lighter alternative to rayon for this specific usecase. There are also utilities for generating the tasks from a slice of data. This library is intended for games and makes no attempt to ensure fairness or ordering of spawned tasks.

It is based on async-executor, a lightweight executor that allows the end user to manage their own threads. async-executor is based on async-task, a core piece of async-std.
