Mike 51201ae54c improve safety comment in scope function (#7534)
# Objective

- While working on scope recently, I ran into a missing invariant for the transmutes in scope. The references passed into Scope are active for the rest of the scope function, but rust doesn't know this so it allows using the owned `spawned` and `scope` after `f` returns. 

## Solution

- Update the safety comment
- Shadow the owned values so they can't be used.

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.
