[Proposal]Drop Xiaomi support?

to @permissions-dispatcher/maintainers and users

Overview

We've been suffering from Xiaomi issues in a past few years. There's no official document, reference and seems like they've changed permission related behavior without any announcement🤔

And according to #533 (comment) the latest MIUI has a system that automatically handles permission dialog on system side👀Not it's a good time to drop Xiaomi handling code from our library? What do you think?

From my point of view:

Props

• Make it easier to maintain
• Simpler logic, less method counts

Cons

• User has to enclose workaround for older MIUI device?

Developers who have to handle newest MIUI system should get the same result with us. I wonder how they fix the problem...

@wangxinghe do you have any insights(sorry to mention you suddenly since I've just seen you gave a star to the library:D)? 🙇
