Add brotli compression (#2646)

[987Nabil]

@jdegoes I think the brotli4j dependency is okay. It would go to the netty backend module once we split zio-http core and netty backend.

@jdegoes I am not sure what the problem with the shading is. Never had to configure it before. Can you give me a hint? The build error is not very helpful.

[jdegoes]

@987Nabil I have not used that setting before, I just know why it's used and how it works.

@987Nabil Please re-open when build is passing. 🙏
