Breakout issue from https://github.com/Esri/calcite-components/pull/807#discussion_r464594337 cc @driskull
setFocus method to handle focus requests instead of the focused propCheckbox
Still valid?
I think we need to increase priority on this one and fix it before release.
@Esri/calcite-components can someone take this one?

@julio8a @macandcheese besides checkbox, it seems like calcite-radio-button needs this change too.
Installed.
@macandcheese Can you help verify this one? 🙇♂️
Works locally on master, thanks!
