shuo 239b070674 Fix asset_debug_server hang. There should be at most one ThreadExecut… (#7825)
…or's ticker for one thread.

# Objective

- Fix debug_asset_server hang.

## Solution

- Reuse the thread_local executor for MainThreadExecutor resource, so there will be only one ThreadExecutor for main thread. 
- If ThreadTickers from same executor, they are conflict with each other. Then only tick one.

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.
