refactor(): remove checked property in favor of parent value (#19449)

BREAKING CHANGE:


The following components have been updated to remove the checked or selected properties:

- Radio
- Segment Button
- Select

Developers should set the value property on the respective parent components in order to managed checked/selected status.
