Fix(WhiteBoard): Prevent Integer display wrapping

[LUwUcifer]

Purpose / Description

#20332 When Android Device Font Size is set to Largest with Default View, Eraser Size Integer wraps at 3 digit numbers

Fixes

Fixes #20332

Approach

1. Changed reviewer.whiteboard.EraserButton layout_width from ?minTouchTargetSize to wrap_content
2. Changed minWidth from 0dp to ?minTouchTargetSize

This approach negates the clipping from the static width of 48dp from minTouchTargetSize and allows for wrapping in case of large fonts, and sets minWidth to minTouchTargetSize to meet Accessibility Criteria

How Has This Been Tested?

This has been tested on a local Android Device of 17.06cm display, width accessibility has been confirmed using Layout Inspector in Android Studio

Learning (optional, can help others)

While considering small texts, setting static widths may cause issues with large default fonts in Accessibility

While checking the app through Google Accessibility Scanner, it did flag some other issues with the whiteboard, is it cool if i work on those too?
