feat(chip): modernize MD3 API

[draggie]

Motivation

Refactors Chip toward the v6/MD3 API and implementation direction.

This change introduces an explicit label prop, extracts Chip-specific tokens, simplifies the internal layout, and removes press-time elevation
animation overhead. It also updates selected, outlined, disabled, icon/avatar, close icon, touch target, and state layer/ripple handling to better align
with Material Design 3.

The example app has been updated to showcase the new API and MD3-oriented Chip states.
