Description of changes

We still have some vestigial code for creating a clipping for Avatar presence and activity badges. This clipping has been hidden away since #2081 but the code was never fully removed. Unfortunately, it can cause some visual artifacting in certain UIKit-based clients running under RTL, so let's take this opportunity to remove it entirely.

Binary change

TBA

Verification

Ensured that Avatar cutouts and badges look correct across various sizes, in both light and dark mode.

Visual Verification

Dark	Light

Pull request checklist

This PR has considered:

• Light and Dark appearances
• iOS supported versions (all major versions greater than or equal current target deployment version)
• VoiceOver and Keyboard Accessibility
• Internationalization and Right to Left layouts
• Different resolutions (1x, 2x, 3x)
• Size classes and window sizes (iPhone vs iPad, notched devices, multitasking, different window sizes, etc)
• iPad Pointer interaction
• SwiftUI consumption (validation or new demo scenarios needed)
• Objective-C exposure (provide it only if needed)
