[BadgeUnstyled] Unstyled API shape discussion

[michaldudak]

When writing the docs for the unstyled badge, a few improvements to the API came to my mind:

• classes prop can be removed to match other unstyled components
• anchorOrigin doesn't do anything except set a class name. I propose to remove it and let developers implement positioning props of their choosing.
• variant="dot" is not necessarily a dot - it must be styled by the developer. Setting badgeContent to an empty string and making the badge smaller would have the same effect. Therefore, variant could be removed from the unstyled component.
• max and showZero make sense only when badgeContent is a number. We could have two overloads of the badge function - one that takes a { badgeContent: number, max?: number, showZero?: boolean } and the other one with { badgeContent?: ReactNode }
• utility classes should have a MuiBadgeUnstyled- prefix

No objection from my side.

I agree with everything. If we remove variant='dot', we only have variant='standard' in unstyled Badge component. Do we need variant prop then?

No, I think we can remove the variant altogether.
