[Feature] Use almost any PHP fw or app with Workerman

Hi Walkor,

I was using a lib internally for more than 2 years, for my legacy apps to run with Workerman v3.5.
https://github.com/joanhey/AdapterMan

This week I tested with frameworks, and It's working perfectly, without touch 1 line of code in the fw or app.

We only need an small change to the Front Controller and PHP 8 as minimum.

Tested with:
- Symfony
- Laravel
- Yii2
- Slim
- KumbiaPHP
- ...

Now I'm creating PRs in the Techempower benchmark.
https://github.com/TechEmpower/FrameworkBenchmarks/pull/7627
https://github.com/TechEmpower/FrameworkBenchmarks/pull/7626
Later I will push Slim and more fws.

I think that this lib will be useful for more people.

If time permits, I'll try to add documentation and upgrade to Workerman v4
