feat(badge): add support for hint feature (#30213)

Issue number: internal

---------

<!-- Please do not submit updates to dependencies unless it fixes an
issue. -->

<!-- Please try to limit your pull request to one type (bugfix, feature,
etc). Submit multiple pull requests if needed. -->

## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->

- Added new position prop.
- Based on the prop, a new badge-position css class is added on the
host.
- Removed css rule that prevented the badge to be rendered when empty.
- Added common and themes styles to support the position prop and new
scale size (on ios/md defaults to min-width variable, as size is not yet
supported on native themes).
- Added new tests specific for this new feature and added new
screenshots.
- Support to properly work inside Avatar, Button and TabButton will be
added on different tasks (in the meantime the snapshots will appear
wrong for these use-cases)
