Description of changes

Currently, PillButtonBar is broken on large text mode and should be relying on its UILargeContentViewerInteraction instead. This change changes the font of the PillButton to not scale with size category changes and use a UILargeContentViewerInteraction.

Binary change

(how is our binary size impacted -- see https://github.com/microsoft/fluentui-apple/wiki/Size-Comparison)

Verification
